5 Alarming Traits of an Unhealthy Relationship (Must-Know)

Key Takeaways:

Control and manipulation are red flags.
Poor communication fuels conflict.
Trust issues weaken emotional bonds.
Boundaries are critical for healthy love.
Emotional intimacy is non-negotiable.

What is an unhealthy relationship?

An unhealthy relationship isn't always about visible signs of abuse or dramatic arguments. Often, it's about the subtle, persistent patterns that slowly chip away at your emotional well-being. You might feel controlled, dismissed, or constantly walking on eggshells to avoid conflict. Does this sound familiar?

In an unhealthy relationship, love becomes a battlefield. Instead of mutual respect and support, it feels like you're stuck in a cycle of fear, manipulation, or emotional distance. The toxic dynamics can be hard to spot at first. But over time, they erode trust, self-esteem, and your sense of safety.

The American Psychological Association defines an unhealthy relationship as one that involves patterns of behaviors where one partner seeks to control, dominate, or harm the other, whether emotionally, physically, or psychologically. These relationships thrive on power imbalances and leave lasting scars.

How do unhealthy relationships develop?

No one steps into a relationship expecting it to turn unhealthy. Yet, many of us find ourselves in this cycle. So, how does it happen? It starts small—like a crack in the foundation. Control might come in the form of “caring too much” or “protecting” you from others, but it slowly morphs into isolation. Emotional abuse creeps in under the guise of teasing, criticism, or dismissing your feelings. Before long, these behaviors become normalized, and we accept them as part of the relationship.

Relationships develop into unhealthy territory often because of deep-seated issues like unresolved trauma, insecurities, or poor communication skills. Psychologist John Gottman, a relationship expert, refers to this as the 'Four Horsemen'—criticism, contempt, defensiveness, and stonewalling—all of which contribute to a relationship's deterioration.

The toxic dynamics of an unhealthy relationship are like weeds—they take root when communication breaks down, when trust is breached, and when control starts to overshadow love. Understanding these patterns can be the first step toward healing or making the decision to move on.

Unhealthy vs healthy relationships: Key differences

At first glance, it might seem easy to distinguish between a healthy and an unhealthy relationship. But often, the differences lie in the subtle behaviors and underlying dynamics that we may overlook. In a healthy relationship, partners support each other's growth, respect boundaries, and communicate openly. There's no place for control, manipulation, or emotional harm.

In contrast, unhealthy relationships thrive on power imbalances and emotional strain. One partner might control the other, either emotionally, financially, or physically. The difference comes down to this: in healthy relationships, love lifts you up; in unhealthy ones, it weighs you down.

For example, in a healthy relationship, arguments are seen as opportunities to understand each other better, while in an unhealthy one, they may spiral into hurtful attacks or manipulation tactics. Dr. Sue Johnson, a renowned psychologist, says, “The best sign of a healthy relationship is emotional responsiveness, where partners are tuned into each other's needs and emotions.” If that connection is absent, problems quickly escalate.

Top 5 traits of an unhealthy relationship

Noticing the red flags of an unhealthy relationship can be challenging, especially when emotions are involved. But it's crucial to recognize these warning signs before they do irreversible damage. Here are the top five traits that commonly define an unhealthy relationship:

Control: This can show up in subtle or overt ways—restricting who you see, what you do, or even how you think. When one partner dominates the other's life decisions, it's a clear sign of an unhealthy dynamic.
Poor Communication: Healthy relationships thrive on open, honest dialogue. In unhealthy ones, silence, avoidance, or constant arguing become the norm, leaving issues unresolved and emotions bottled up.
Emotional Abuse: Insults, belittling, and gaslighting are forms of emotional abuse that degrade a partner's self-worth. This type of behavior leaves deep psychological scars that are hard to heal from.
Dishonesty: Lies, secrecy, or constant deception erode trust—the backbone of any relationship. If you find yourself questioning your partner's honesty, it's a significant red flag.
Lack of Respect: Disrespect can take many forms—talking down, mocking, or dismissing your feelings. Respect is essential for emotional safety, and without it, a relationship can never be truly healthy.

It's important to pay attention to these signs. If more than one trait resonates with your relationship, it's time to reflect on your next steps.

How control leads to toxic dynamics

Control in a relationship doesn't always look like aggressive demands or outright manipulation. It can be subtle—disguised as “concern” or “protection.” You may start to notice that your partner dictates who you spend time with, what you wear, or even how you spend your free time. At first, it might feel like they're looking out for you, but over time, this control slowly chips away at your freedom and autonomy.

Control often leads to an unbalanced power dynamic, where one person holds all the decision-making power and the other feels trapped or limited. When control enters a relationship, it fosters an environment of fear, resentment, and dependency. Instead of two equal partners working together, the relationship turns into one person manipulating the other's behavior to fit their needs.

This kind of toxic dynamic can also affect how you see yourself. You might feel like you have to walk on eggshells, constantly seeking approval or trying to avoid criticism. Psychologist Harriet Lerner explains, “When one person in a relationship constantly holds the power, it creates a cycle of oppression and resentment, damaging the emotional connection.”

Recognizing the signs of control is critical to breaking free from toxic dynamics. If your partner is making you feel powerless or isolated, it's a sign of an unhealthy relationship that may worsen over time.

Emotional abuse: Warning signs you can't ignore

Emotional abuse often flies under the radar because it leaves no visible scars, yet its impact is just as destructive. It's not just about hurtful words; emotional abuse includes constant criticism, manipulation, humiliation, and gaslighting—where your partner makes you question your reality or sanity.

Emotional abuse creates a deep sense of insecurity and self-doubt. You might find yourself apologizing constantly, even when you haven't done anything wrong. You start to believe that you're too sensitive or that your feelings don't matter. This gradual erosion of self-esteem is exactly what makes emotional abuse so harmful.

One of the most common signs of emotional abuse is the feeling that nothing you do is ever good enough. Your partner may belittle your achievements, downplay your emotions, or dismiss your concerns. The goal is to make you feel small, powerless, and dependent on their approval.

As therapist Beverly Engel writes in her book, The Emotionally Abusive Relationship, “Emotional abuse is an assault on the soul, a violation of the spirit, and the systematic tearing down of a person's sense of self.” Don't overlook these warning signs—emotional abuse is never acceptable, and it often escalates if left unchecked.

The effects of physical abuse in a relationship

Physical abuse is one of the most visible and devastating forms of harm in a relationship. It often begins with small, seemingly isolated incidents, such as pushing or grabbing, but quickly escalates into more severe acts of violence. Physical abuse doesn't just cause immediate harm—it leaves deep emotional scars that can last a lifetime. Each act of violence erodes the sense of safety and trust, leaving the victim feeling trapped, fearful, and helpless.

When physical abuse enters a relationship, the dynamic changes drastically. Love turns into fear, and intimacy is replaced by constant anxiety. Victims of physical abuse may find themselves in a cycle of guilt, shame, and confusion, often blaming themselves for the violence.

According to the National Domestic Violence Hotline, physical abuse in a relationship is about power and control, and it's never the victim's fault. Yet, many people stay in these relationships, hoping things will change or fearing the consequences of leaving. The physical wounds may heal, but the psychological trauma can linger for years, affecting the way a person views themselves and others.

If you or someone you know is experiencing physical abuse, seek help immediately. There is no justification for violence, and no one deserves to live in fear.

Dishonesty: How lies erode trust and connection

Trust is the foundation of any healthy relationship. When dishonesty enters the picture, it quickly erodes the bond between partners. Lies, whether big or small, create an atmosphere of suspicion and insecurity. The more lies are told, the harder it becomes to rebuild trust and maintain a genuine connection.

Dishonesty can take many forms—omitting the truth, exaggerating details, or outright lying. Over time, these behaviors can cause serious damage. One lie may lead to another, and soon enough, the entire relationship becomes a house of cards built on deceit. You begin to question everything—every word, every action, every motive.

Renowned psychologist and relationship expert Dr. John Gottman highlights that “trust is built in very small moments, but it can be shattered in an instant.” Lies, even those intended to avoid conflict, can break down the emotional connection between partners. Once trust is broken, it takes immense effort to rebuild, if it can be rebuilt at all.

The constant fear of discovering more lies can create emotional distance and push partners further apart. If you find yourself questioning your partner's honesty, it's essential to address it. Open, transparent communication is the only way to restore trust and strengthen your connection.

Disrespect and belittling behavior in partnerships

Disrespect can take many forms in a relationship, and belittling behavior is one of the most toxic. Whether it's mocking your opinions, making fun of your aspirations, or constantly putting you down in front of others, belittling behavior sends a clear message: your partner doesn't value or respect you. Over time, this kind of behavior eats away at your self-esteem and creates a profound emotional distance.

In a healthy relationship, partners lift each other up. But when disrespect enters the dynamic, it becomes a power play. The person who belittles often feels the need to dominate or control the narrative, using hurtful words or actions to maintain that control. They might disguise their behavior as “just joking,” but you're left feeling small and humiliated.

Respect is fundamental to a thriving relationship. When it's lacking, it's hard to feel safe or appreciated. As author Brené Brown states, “Vulnerability is the birthplace of connection and the path to the feeling of worthiness. If we're not willing to be vulnerable, we lose the opportunity to truly connect.” In relationships marked by disrespect, that vulnerability is stifled, and true emotional intimacy becomes impossible.

Sexual violence and crossing boundaries

Sexual violence is an extreme violation of trust, boundaries, and personal safety. It can take many forms—from coercion and manipulation to outright assault—and it leaves profound emotional and physical scars. In a relationship, sexual violence is not just about sex; it's about power, control, and the complete disregard for a partner's autonomy and consent.

Sexual violence often goes hand in hand with other forms of abuse, making it a part of a broader pattern of controlling behavior. Many victims find themselves feeling isolated, ashamed, and afraid to speak out. The trauma from these experiences can lead to long-term emotional damage, including anxiety, depression, and post-traumatic stress disorder (PTSD).

Consent is non-negotiable in any healthy relationship. If your partner pressures or forces you into any sexual activity without your enthusiastic and informed consent, this is a clear violation of your boundaries. No one has the right to your body, and your comfort and safety should always come first.

If you're experiencing sexual violence in your relationship, it's vital to seek help and support. Your safety and well-being matter, and there are resources available to help you navigate this painful situation.

The dangers of manipulation in a relationship

Manipulation in a relationship is often subtle, but it's one of the most insidious forms of control. It can look like guilt-tripping, gaslighting, or making you feel responsible for your partner's emotions. You might find yourself constantly second-guessing your decisions, wondering if you're being too “selfish” or not doing enough. The truth is, manipulation erodes your confidence and takes away your sense of autonomy.

Manipulators are skilled at making you doubt your reality. They might twist situations to make themselves look like the victim or convince you that you're overreacting. This emotional manipulation can leave you feeling confused, disoriented, and powerless. Over time, it chips away at your sense of self and leaves you dependent on your partner for validation.

It's important to recognize manipulation for what it is—a toxic power dynamic designed to keep you under control. If you feel like your partner is always “winning” arguments or you're constantly apologizing, it might be time to evaluate whether manipulation is at play. In the words of Dr. Robin Stern, author of The Gaslight Effect, “When you're gaslit, you start to believe the version of reality that your abuser wants you to believe, and it takes a toll on your mental health.”

Identifying manipulation is the first step in breaking free from its grip and reclaiming your voice in the relationship.

Isolation: When love cuts you off from others

One of the most dangerous tactics in an unhealthy relationship is isolation. It often starts innocently enough—your partner wants to spend more time with you, or they're “concerned” about the people you hang out with. But over time, these “concerns” become restrictions, and you find yourself cut off from your friends, family, and support networks.

Isolation is a powerful tool used by controlling partners to make you dependent on them. By severing your connections with others, they limit your access to outside perspectives and support. You might find yourself making excuses for why you no longer see your friends or spend time with family, but the real reason is that your partner has created a bubble around your life, one where they hold all the control.

Love should never make you feel isolated or alone. In fact, a healthy relationship supports and encourages outside friendships and activities. If your partner is trying to isolate you, it's a major red flag that something is wrong. As therapist and author Lundy Bancroft notes, “Isolation is a key component of abusive relationships, because it takes away your freedom and keeps you in a constant state of dependency.”

Breaking out of isolation can be difficult, but reconnecting with your support network is essential for your emotional well-being. You deserve a relationship that celebrates your independence, not one that tries to erase it.

Why healthy boundaries are non-negotiable

Boundaries are the invisible lines that protect our emotional, mental, and physical well-being. They define what we're comfortable with and what we aren't. In a healthy relationship, boundaries are respected and even celebrated because they create a sense of safety and trust. But in an unhealthy relationship, boundaries are often ignored or trampled over.

When your partner disrespects your boundaries, it sends a message that your needs and limits don't matter. This can be as subtle as dismissing your feelings or as blatant as pressuring you into doing things you're uncomfortable with. Over time, this erosion of boundaries leads to resentment, burnout, and emotional exhaustion.

Setting boundaries isn't about putting up walls—it's about defining your personal space and making it clear what you need to feel secure. As therapist Nedra Glover Tawwab explains, “Boundaries aren't about controlling others; they're about protecting yourself.” When you have healthy boundaries, you can engage in relationships from a place of strength and self-respect.

If your partner regularly crosses your boundaries, it's a sign that the relationship isn't balanced. Remember, boundaries are non-negotiable. They're essential to maintaining your identity and emotional health within any partnership.

Lack of trust: The slow poison of any relationship

Trust is the foundation on which every relationship stands. Without it, even the strongest connection can crumble. When trust is lacking, it's like a slow poison that gradually seeps into every interaction. You find yourself questioning your partner's motives, second-guessing their actions, and feeling uneasy about their words. Over time, this lack of trust turns into suspicion and anxiety, making it impossible to build a healthy, lasting bond.

Trust issues often arise from past betrayals, whether in the current relationship or previous ones. But regardless of where the mistrust stems from, it can deeply affect the dynamics of your partnership. The absence of trust leaves both partners feeling vulnerable and disconnected, making every small conflict feel like a much larger issue.

Rebuilding trust is difficult, but not impossible. It requires consistent, honest communication and a commitment to transparency. Without trust, though, the relationship can never feel truly safe. As relationship expert Esther Perel says, “Trust isn't just about being faithful—it's about being emotionally reliable.” If you can't rely on your partner to be there for you emotionally, the relationship may be built on shaky ground.

In relationships where trust has eroded, it's crucial to address the root causes. Without doing so, mistrust will continue to poison the connection, leading to an eventual breakdown.

Unrealistic expectations in romantic relationships

We all have hopes and dreams when we enter a relationship, but unrealistic expectations can quickly derail even the most promising partnership. These expectations often stem from romanticized ideas about love or a desire for our partner to fulfill all of our emotional needs. However, expecting perfection from your partner—or yourself—sets the stage for disappointment and frustration.

Unrealistic expectations can manifest in many ways. You might expect your partner to always know how you feel without you having to communicate it, or you might expect them to “complete” you in every way. When these expectations aren't met, it leads to resentment and dissatisfaction. Relationships thrive on realistic expectations, where both partners understand that growth and support take effort.

As therapist and author Terrence Real points out, “We live in a culture that promotes the fantasy of perfect love, but real love is about imperfection, patience, and acceptance.” The key to avoiding this pitfall is managing your expectations and focusing on mutual respect, communication, and growth. If you or your partner are constantly feeling let down, it may be time to evaluate whether your expectations are aligned with reality.

Poor communication: Why it's the biggest red flag

Communication is the heartbeat of any relationship. Without it, misunderstandings build up, resentment festers, and emotional distance grows. Poor communication often starts with small breakdowns—avoiding difficult conversations, keeping feelings bottled up, or passive-aggressive behavior. Over time, these habits create an environment where real connection becomes impossible.

When communication breaks down, both partners can feel unheard, misunderstood, or unappreciated. This can lead to defensiveness or stonewalling, where one person shuts down emotionally. The longer these issues go unaddressed, the harder it becomes to repair the damage. In fact, according to Dr. John Gottman's research, poor communication is one of the leading predictors of divorce and relationship breakdowns.

Healthy communication isn't just about talking—it's about listening, empathizing, and working through conflicts constructively. When couples learn how to communicate effectively, they create a foundation for resolving issues and deepening their emotional intimacy. If you notice that your relationship is filled with miscommunication or unresolved arguments, consider it a significant red flag. It's never too late to improve communication, but both partners need to be willing to do the work.

Competition and its negative impact on love

Relationships are meant to be partnerships, not rivalries. When competition seeps into a relationship, it creates a toxic dynamic where both partners feel like they're constantly trying to one-up each other. Whether it's about who makes more money, who does more around the house, or even who is more “successful,” competition undermines the supportive foundation that love is built on.

Competition shifts the focus from teamwork to winning, and that mindset is destructive in a romantic relationship. Instead of celebrating each other's achievements, competitive partners may feel jealousy or resentment. You may begin to keep score—counting every little thing you do and comparing it to what your partner does. This creates emotional distance and kills the sense of unity that love thrives on.

True love isn't about being better than your partner; it's about growing together. As author and speaker Simon Sinek says, “A team is not a group of people that work together. A team is a group of people that trust each other.” If your relationship feels more like a competition than a partnership, it's time to reassess the dynamics and focus on collaboration, not rivalry.

Cheating: When infidelity breaks a bond

Cheating is one of the most painful betrayals in a relationship. It breaks the trust that forms the foundation of any partnership and leaves deep emotional scars that can take years to heal. When infidelity enters a relationship, it creates a ripple effect of hurt, anger, and confusion. It doesn't just hurt the person who was cheated on—it can leave the unfaithful partner grappling with guilt and regret.

Infidelity isn't just about the physical act; it's the breach of emotional trust that hurts the most. When someone cheats, they break the emotional contract that promised loyalty and honesty. Even if the relationship survives the affair, rebuilding trust is a long and difficult process. Many couples find that the emotional aftermath of cheating is harder to navigate than the act itself.

In her book State of Affairs, therapist Esther Perel notes, “Affairs are not so much about sex, but about desire—the desire to feel alive, to escape, to experience something new.” While this may explain why cheating happens, it doesn't justify the emotional devastation it causes. Infidelity often signals deeper issues in the relationship—unresolved conflicts, unmet needs, or emotional disconnection.

If cheating has broken the bond in your relationship, you have to decide whether rebuilding trust is possible and whether both partners are committed to that process. Trust can be restored, but it requires transparency, accountability, and a willingness to heal the deep emotional wounds caused by the betrayal.

The obsession trap: When love turns into fixation

There's a fine line between deep love and obsession. When love turns into fixation, it stops being about mutual respect and connection and becomes about control, possession, and unhealthy attachment. Obsession often masquerades as passion, but underneath it lies insecurity, jealousy, and the need to dominate your partner's time and attention.

An obsessive partner may demand constant reassurance, need to know your every move, or feel threatened by your other relationships and interests. This level of fixation can be suffocating, making you feel trapped rather than loved. Obsession isn't about nurturing the relationship; it's about feeding personal insecurities at the expense of your partner's freedom and autonomy.

Love should allow room for individuality, growth, and independence. As psychoanalyst Erich Fromm once said, “Love is an act of faith, and whoever is of little faith is also of little love.” Obsession, on the other hand, comes from a place of fear and insecurity, not trust. When love turns into fixation, it's a sign that the relationship is moving into dangerous territory where control overshadows genuine care.

Emotional intimacy: Why its absence signals trouble

Emotional intimacy is the lifeblood of any strong relationship. Without it, the relationship becomes hollow, lacking depth and connection. Emotional intimacy is about being able to share your inner world with your partner—your fears, dreams, insecurities, and joys—and knowing that they'll listen, understand, and support you. It's what turns a romantic partnership into a true emotional bond.

When emotional intimacy is missing, it leaves a void that no amount of physical attraction or surface-level communication can fill. You might feel like you're just going through the motions with your partner—living together, talking, but not truly connecting on a deeper level. Over time, the absence of emotional intimacy can lead to feelings of loneliness, dissatisfaction, and emotional disconnection, even when you're physically close.

Research shows that couples who maintain emotional intimacy are better able to weather the challenges of life together, while those who lack it often struggle to sustain their bond. Relationship expert Dr. Sue Johnson emphasizes the importance of emotional safety in relationships: “Emotional responsiveness is the key to creating a loving bond. When you feel emotionally secure, you know your partner has your back.”

If emotional intimacy is lacking in your relationship, it's a warning sign that things need to change. Rebuilding that connection requires vulnerability, trust, and open communication. Without it, love starts to feel empty, and the relationship slowly drifts apart.

What to do if you're in an unhealthy relationship

Realizing that you're in an unhealthy relationship is difficult, but it's the first step toward reclaiming your emotional well-being. If you recognize the signs—whether it's manipulation, control, abuse, or a lack of respect—it's important to take action. The first thing you need to know is that you deserve a relationship where love, trust, and respect are mutual.

If you're feeling unsure about the next steps, start by reaching out to someone you trust. Whether it's a close friend, family member, or therapist, having a support system can help you process your feelings and make informed decisions. Don't try to handle everything on your own—isolating yourself can make it harder to break free from toxic dynamics.

Setting boundaries is another key step. Make it clear what behavior is unacceptable and stick to those boundaries. If your partner continues to violate them, it may be time to consider leaving the relationship. While ending a relationship is never easy, staying in an unhealthy one can do long-term damage to your mental and emotional health.

For those experiencing abuse—whether emotional, physical, or sexual—seeking professional help is critical. Reach out to local resources or hotlines that specialize in relationship abuse. Your safety and well-being are the top priority.

FAQs about unhealthy relationships

Is my relationship healthy or unhealthy?

It can be hard to tell when you're in the middle of it, but a healthy relationship makes you feel valued, respected, and supported. In contrast, an unhealthy relationship often leaves you feeling controlled, belittled, or disconnected. Trust your instincts—if something feels off, it probably is.

Why do I avoid healthy relationships?

If you find yourself consistently drawn to unhealthy relationships, it could stem from past trauma, unresolved emotional issues, or self-esteem struggles. Therapy can help uncover the reasons behind this pattern and teach you how to build healthier connections moving forward.

What is an unhealthy boy-girl relationship?

An unhealthy boy-girl relationship, like any unhealthy partnership, is characterized by a lack of mutual respect, trust, and emotional support.
