How do you define insecurity in a relationship?

Insecurity in a relationship can feel like an invisible wall between you and your partner. It's that sinking feeling that creeps in, making you question whether you're truly enough or if your partner will leave you for someone "better." At its core, insecurity stems from a deep-rooted fear—fear of rejection, abandonment, or not being worthy of love.

It's important to note that relationship insecurity doesn't always show up in obvious ways. Sometimes it hides behind over-analyzing every little action or word from your partner, or feeling anxious when they're not around. Whether subtle or extreme, insecurity can quietly sabotage the connection you have with your partner. As relationship therapist Esther Perel puts it, “The quality of your relationships determines the quality of your life.” If insecurity is left unchecked, it can erode even the strongest bonds.

What causes a person to feel insecure in the relationship?

There's no single reason why someone might feel insecure in their relationship. Often, it's a mix of past experiences and current fears. Maybe you've been hurt before, perhaps by a partner who betrayed your trust, or maybe it's a personal struggle with low self-esteem that's trickled into your relationship. Either way, these experiences tend to create a lens of fear through which we view our partners' actions.

Attachment theory, first proposed by psychologist John Bowlby, suggests that the way we bond with caregivers as children affects how we behave in adult relationships. If you had an insecure attachment growing up, you might carry that into your romantic relationships, constantly worrying about abandonment or needing excessive reassurance. It's not uncommon for someone with insecurity to seek validation in ways that push their partner further away, creating a vicious cycle.

External factors like societal pressures, comparisons on social media, or seeing friends' "perfect" relationships can also amplify insecurities. What we don't realize is that everyone faces challenges behind the scenes. Comparing your relationship to others only fuels the insecurity fire, leaving you in a constant state of self-doubt.

Where do relationship insecurities come from?

Relationship insecurities often have deep roots. They can stem from childhood experiences, past relationships, or even societal pressures. Many times, we don't even realize how far back these insecurities go until we take a moment to reflect. It's not just about the here and now, but also how we've been shaped by previous emotional bonds and experiences.

Psychologists often talk about "attachment theory," which suggests that our early interactions with caregivers shape our sense of security in relationships. If you experienced inconsistent love or were constantly anxious about abandonment in your childhood, it's likely those feelings will resurface in your romantic life.

Even personal setbacks—like being cheated on in a previous relationship—can plant seeds of doubt. We start to project those past betrayals onto our current partner, even if they've done nothing to deserve it. Social media comparisons only amplify these insecurities, feeding into the idea that other relationships are perfect while ours is lacking.

Examples of insecurity in a relationship

Insecurity can show up in various ways. Sometimes it's subtle, like feeling uneasy when your partner doesn't text back right away. Other times, it's more obvious—constant jealousy or asking for reassurance daily.

One of the biggest red flags of insecurity is the need for control. You might start demanding access to your partner's phone or social media, feeling like you need proof they're not hiding anything. But this isn't healthy; it erodes trust over time.

Other examples include feeling paranoid when your partner is out with friends, assuming they're cheating or lying. Some people even test their partners, intentionally creating situations to see how they react. These behaviors push partners away, increasing distance instead of fostering closeness.

Is feeling insecurity normal in a relationship?

Yes, feeling insecure in a relationship is actually more common than we'd like to admit. At some point, we all experience moments of doubt or fear. Insecurity can arise even in the healthiest relationships—it doesn't mean there's something inherently wrong with the relationship itself. But when it becomes a recurring theme, it's important to take a step back and look at what's fueling these feelings.

What's key is how we handle that insecurity. When we let those doubts drive our actions—like constantly needing validation or being overly suspicious—we start to create problems that weren't there to begin with. On the other hand, recognizing and addressing these insecurities can actually lead to growth, both individually and as a couple.

Even the most confident individuals feel vulnerable sometimes. The difference lies in how we choose to respond to those feelings. Instead of letting insecurity rule, we can choose to open up, communicate, and face it head-on. It's about working through the fear instead of letting it define the relationship.

16 Signs of insecurities in a relationship

Insecurity can manifest in many forms, some more obvious than others. Here are 16 key signs that insecurity is creeping into your relationship:

1. Fear of losing your partner: Constant worry they'll leave you.
2. Consuming jealousy: Feeling threatened by anyone who interacts with your partner.
3. Negativity: You expect the worst in your relationship, assuming it won't last.
4. Demanding access to gadgets: Needing to check their phone, emails, or social media.
5. Constantly checking social media: Monitoring their online activity to find clues about what they're doing.
6. Paranoia about your partner's whereabouts: Overly suspicious when they go out or are away from you.
7. The need for constant reassurance: Always seeking affirmation that they still love you or aren't leaving.
8. You don't like being left alone: Feeling anxious when they're not around, even if it's for short periods.
9. Avoiding confrontation: You'd rather ignore issues than risk rocking the boat.
10. Suspecting everyone: You believe anyone could be a potential threat to your relationship.
11. Doubting your partner's loyalty: You question their faithfulness even when there's no clear reason to.
12. There's always an issue: You find yourself bringing up new problems frequently, even over minor things.
13. Testing your partner: You set up scenarios to see how they'll respond, to test their commitment.
14. Vulnerability to cheat: Sometimes insecurity drives people to cheat as a way to feel desirable again.
15. Difficulty with intimacy: Struggling to fully connect emotionally or physically due to trust issues.
16. Not feeling happy: Insecurity leaves you feeling unsatisfied and disconnected in the relationship.

While these signs don't always mean the relationship is doomed, recognizing them is the first step to healing and moving toward a healthier, more secure connection with your partner.

Fear of losing your partner

The fear of losing your partner can be paralyzing. It's the kind of insecurity that makes you constantly doubt whether you're good enough or if your partner is already halfway out the door. This fear often stems from personal insecurities or past experiences of abandonment. Even if your partner has given you no reason to believe they'd leave, you still might find yourself imagining worst-case scenarios.

This type of fear manifests in behaviors like clinging too tightly or over-analyzing every interaction, seeking signs that something is wrong. For example, if they don't text back immediately, you might jump to the conclusion that they've lost interest. But the truth is, these fears are more about you than they are about your partner's actions.

As relationship expert Brené Brown once said, “When we shut down vulnerability, we distance ourselves from the experiences that bring purpose and meaning to our lives.” When we fear losing our partner, we sometimes overcompensate, becoming more controlling or needy. But by doing so, we end up creating the very distance we're trying to avoid.

Consuming jealousy

Jealousy is one of the most toxic symptoms of insecurity in a relationship. When it becomes consuming, it can feel like an uncontrollable force, driving irrational thoughts and behaviors. This kind of jealousy isn't about fleeting moments of envy—it's a constant state of suspicion, often assuming the worst about your partner's intentions or interactions with others.

You may find yourself scrutinizing every text, every glance, or even casual conversations with others. Consuming jealousy can lead to intense arguments, especially if you accuse your partner of things they haven't done. It's an exhausting and vicious cycle that makes you feel powerless, pushing your partner further away.

Psychologist and author Harriet Lerner explains, “Jealousy is an emotion that all of us feel from time to time. The key is to recognize it and work through it before it spirals into controlling behavior.” The trick is learning to manage these feelings before they damage the trust that's foundational to your relationship. Left unchecked, jealousy can erode even the strongest connections.

Negativity

Negativity in a relationship is like a dark cloud hanging over everything, and it often stems from deep-rooted insecurities. When you're constantly worried that things will fall apart, you start to expect the worst in every situation. Even when things are going well, you may find yourself anticipating an argument or expecting your partner to disappoint you.

Living in this negative mindset can prevent you from enjoying the good moments in your relationship. It's as if you're always bracing yourself for heartbreak, even when there's no immediate reason for concern. This outlook not only affects your emotional well-being but also creates unnecessary tension with your partner, who may feel as though they can never do enough to make you happy.

As therapist Amy Morin suggests, “Negative thoughts and emotions are inevitable, but how we respond to them makes all the difference.” Shifting your mindset to focus on what's going right in your relationship can help break the cycle of negativity. Instead of assuming the worst, allow yourself to celebrate the positives without fear of what could go wrong.

Demanding access to gadgets

One of the clearest signs of insecurity is the demand to access your partner's gadgets—phones, emails, and social media accounts. This behavior comes from a place of mistrust, where you feel the need to "verify" your partner's loyalty through surveillance. If you constantly ask for their phone to check texts or scan through their social media, it shows a lack of trust and respect for boundaries.

While open communication and transparency are important, demanding access to gadgets crosses the line into controlling behavior. It sends the message that you don't trust them to be honest or faithful. This habit may temporarily relieve your anxiety, but it's a short-lived solution that often leads to resentment from your partner.

According to psychologist Dr. John Grohol, “Trust is a fragile thing. Once it's damaged, it can take a long time to rebuild.” By demanding constant access to your partner's personal devices, you risk damaging the very trust that's necessary for a healthy relationship. Rather than relying on surveillance, it's far better to address the root cause of your insecurity and communicate openly about your concerns.

Constantly checking social media

One of the most modern symptoms of relationship insecurity is the obsession with checking your partner's social media. If you find yourself scrolling through their feeds, looking for clues about their whereabouts or interactions, you're not alone. Social media can fuel insecurity by creating a distorted sense of reality where we compare our relationship to carefully curated snapshots of others' lives.

Constantly monitoring your partner's online activity—who they're liking, commenting on, or messaging—can quickly become toxic. Instead of trusting your partner, you begin to rely on these digital breadcrumbs as "evidence" of their loyalty or infidelity. But social media doesn't tell the whole story, and basing your trust on what you find there often leads to unnecessary conflict.

According to relationship expert Dr. Sue Johnson, “Trust and communication are the foundations of a strong relationship.” Social media shouldn't be the measure of your partner's commitment. Instead, fostering direct conversations about any concerns can go a long way in building real trust and letting go of the digital obsession.

Paranoia about partner's whereabouts

When insecurity takes over, paranoia about your partner's whereabouts can become all-consuming. You might find yourself constantly wondering, "Where are they?" or "Who are they with?" These thoughts can spiral out of control, even if your partner has given you no reason to doubt them.

Paranoia is fueled by fear—fear of being lied to, fear of infidelity, or fear of abandonment. It can manifest in behaviors like calling or texting your partner frequently when they're out, demanding they share their location, or interrogating them when they come home. While it may seem like a protective measure, it actually suffocates the trust in your relationship.

Psychologist David Richo explains, “Paranoia is often a defense against feelings of helplessness. It creates the illusion of control.” But in reality, this control is an illusion that pushes your partner away. Learning to cope with your fears and addressing them openly with your partner is essential for breaking free from this cycle of paranoia.

The need for constant reassurance

When insecurity takes hold, it often leads to an overwhelming need for constant reassurance. You may find yourself frequently asking questions like, "Do you still love me?" or "Are you sure you won't leave?" This need for validation can become exhausting for both you and your partner, creating a cycle of dependency that weakens the foundation of the relationship.

While it's normal to want occasional affirmation from your partner, constantly seeking it can be a sign of deeper insecurity. Instead of feeling confident in the love you share, you rely on external validation to feel secure. This places immense pressure on your partner to constantly prove their commitment, which can lead to frustration and emotional burnout.

Renowned relationship expert Dr. John Gottman once said, “The goal is not to seek reassurance but to build trust in a way that makes reassurance unnecessary.” Learning to trust in your partner's actions and in the strength of your bond can help you move away from this endless need for affirmation.

You don't like being left alone

Another common sign of insecurity is discomfort or anxiety when your partner leaves you alone. Whether it's them going out with friends, traveling for work, or even stepping away for a few hours, being apart can trigger feelings of abandonment or fear that they might find someone else.

Feeling uneasy when your partner isn't around often stems from past experiences of being let down or left behind. It may also point to a lack of trust or a fear of not being able to cope emotionally without them. But constantly needing to be with your partner can suffocate both of you and hinder your individual growth.

It's crucial to find a balance between spending time together and allowing for personal space. As author Esther Perel puts it, “The quality of the relationship depends on the ability to navigate togetherness and separateness.” Learning to embrace alone time not only strengthens the relationship but also builds your own sense of independence and security.

Avoiding confrontation

Avoiding confrontation is a common sign of insecurity in a relationship. You may shy away from difficult conversations because you're afraid of conflict or worried that addressing issues might push your partner away. The problem is that avoiding confrontation only allows problems to fester beneath the surface, creating even more tension over time.

While it's understandable to want to keep the peace, avoiding tough discussions can damage the trust and communication necessary for a healthy relationship. You might think staying silent will prevent an argument, but it often leads to resentment, passive-aggressive behavior, and even a greater emotional distance between you and your partner.

As marriage counselor Dr. Gary Chapman notes, “Effective communication is the key to healthy conflict resolution in any relationship.” Instead of sweeping issues under the rug, it's important to embrace the discomfort of difficult conversations and work through them together. By addressing concerns directly, you build a stronger, more open connection.

Doubting partner's loyalty

Constantly doubting your partner's loyalty is another clear sign of insecurity. Even if your partner has given you no reason to question their faithfulness, you might still find yourself wondering if they're being honest with you. This can lead to obsessive thoughts, questioning their every move, or accusing them of cheating without any evidence.

This type of doubt can severely undermine a relationship. When you constantly question your partner's loyalty, it shows a lack of trust and pushes your partner away. No relationship can thrive without a solid foundation of trust, and once it's damaged, it can be incredibly difficult to repair.

Instead of letting your doubts spiral, it's important to communicate openly with your partner about your concerns. Relationship expert Shirley Glass reminds us that, “Trust is built when someone is vulnerable and not taken advantage of.” By choosing to be vulnerable and addressing your doubts, you can start to rebuild trust and overcome the insecurity that's driving your fears.

You test your partner's behavior

Testing your partner's behavior is a subtle yet harmful way insecurity shows up in relationships. You might create situations to gauge how much they care or if they will stay loyal. For example, you might intentionally act distant to see if they'll chase after you, or you might cancel plans last minute to test their reaction. While these tests may seem harmless, they often backfire, creating unnecessary tension and confusion.

Testing your partner undermines trust and can lead to frustration, as they feel like they're constantly being judged or set up to fail. It also creates a dynamic where you're looking for proof of their love instead of trusting it. Over time, this behavior erodes the natural flow of the relationship, making both of you feel insecure.

According to psychologist Dr. Judith Orloff, “When we test our partner, we're not looking for answers but for reassurance that we can't give ourselves.” Instead of relying on these games, it's healthier to address your insecurities directly and seek reassurance through honest communication, not manipulation.

Vulnerability to cheating

In some cases, insecurity can make you more vulnerable to cheating. This may seem counterintuitive, but the fear of not being enough for your partner or the worry that they may cheat on you can lead to seeking validation elsewhere. Cheating becomes a way to soothe your feelings of inadequacy or to regain a sense of control in the relationship.

It's a slippery slope—one that doesn't solve the underlying insecurity but worsens it. Cheating not only damages your current relationship but also leaves you feeling more disconnected from yourself and others. The thrill of temporary validation fades quickly, and what's left is guilt and a deeper sense of insecurity.

As relationship coach Esther Perel explains, “Infidelity isn't just about sex; it's about desire—the desire for attention, validation, or to feel alive again.” However, these desires can be fulfilled in healthier ways through open communication and addressing the root of your insecurities. Rather than acting on impulses, it's crucial to confront the fears and doubts that are driving those feelings.

Struggling with intimacy

Insecurity can deeply affect your ability to connect intimately with your partner. When you're constantly doubting yourself or your relationship, it becomes hard to fully open up, both emotionally and physically. You might find yourself pulling away during moments of closeness or avoiding vulnerable conversations because you're afraid of being judged or hurt.

Intimacy is all about trust, and when insecurity creeps in, it erodes that trust. Whether it's fear of rejection, body image concerns, or emotional walls, these insecurities make it difficult to experience real closeness with your partner. Over time, this can lead to feelings of isolation, even when you're together.

Sex therapist Dr. Ian Kerner notes, “Intimacy is built on vulnerability, and vulnerability requires feeling safe enough to be seen and accepted for who we are.” When insecurity disrupts intimacy, it's important to address those fears and work towards rebuilding trust. Only then can true closeness and connection flourish.

How to overcome insecurities in relationships

Overcoming insecurities in relationships is not an overnight process, but it's entirely possible with effort and self-awareness. The first step is acknowledging that these insecurities exist. Trying to bury or ignore them only allows them to grow stronger over time.

One of the most effective ways to tackle insecurity is through open communication. Talk to your partner about your fears, but avoid blaming them for your insecurities. Instead, frame the conversation around how you feel and what you need in terms of support. Often, sharing these feelings can bring you closer together and help your partner understand what's going on beneath the surface.

Another important step is working on your own self-esteem. Insecurities often stem from how we feel about ourselves, not necessarily from the actions of our partner. Practicing self-care, setting healthy boundaries, and even seeking therapy can help you build confidence and reduce those feelings of inadequacy.

As clinical psychologist Dr. Guy Winch says, “The key to overcoming relationship insecurity is learning to trust not just your partner, but yourself.” Trust in your ability to navigate challenges, communicate your needs, and build a relationship based on mutual respect. Over time, this trust will help dissolve the insecurities that have been holding you back.

Can insecurities ever disappear completely?

The honest answer is: insecurities may never completely disappear, but they can be managed and significantly reduced. Just like any emotional struggle, insecurity is something we can learn to cope with rather than letting it control our lives. Insecurities are often tied to our personal history and deep-rooted fears, which can resurface from time to time, even in the most stable relationships.

However, with consistent self-work, including building self-esteem and trust, you can learn to minimize the impact of insecurity on your relationship. Over time, the things that once triggered feelings of doubt or fear will lose their power as you strengthen your sense of self-worth and deepen your connection with your partner.

Therapist Lori Gottlieb shares that “emotional health is not about eliminating every negative emotion, but learning how to handle them when they arise.” In other words, the goal isn't perfection, but growth. Insecurities can become much less significant when you focus on personal development and building trust, both in yourself and in your partner.

Conclusion

Insecurities in relationships are far more common than many of us realize. Whether it's the fear of losing your partner, consuming jealousy, or struggling with intimacy, these feelings stem from deeper emotional fears that need to be addressed. The good news is that while insecurities may always be part of the human experience, they don't have to control your relationships.

By acknowledging your insecurities, communicating openly, and building trust with your partner, you can navigate these challenges and come out stronger on the other side. It's not about erasing all fear, but about learning how to live with it and, more importantly, how to grow beyond it.

Overcoming insecurity takes time, patience, and self-compassion. It requires understanding yourself, working on self-worth, and trusting the bond you've built with your partner. As you grow together, you'll find that your insecurities no longer have the power to define your relationship.
