Thank you for your advice. The thing that amazes me is that she has a life, a profession, many friends, family etc and yet she always takes time to message me 20 times a day minimum, call me at every possible moment she can, call me to make sure I got up in the morning and so much more. She talks about the future, about being old together, about our little odd habits and so much more.
However, once we go to bed we cuddle and hold and she snuggles up to me and hold me tight, she does not respond to any kind of make out move. She does not say no but is totally unresponsive which is obviously a stop sign in itself.
It is not the lack of sex because that is not a dealbreaker at this stage, but it is the lack of even the most basic make out that makes me wonder whether she actually does want me and I am not just a "nice guy" safe option to grow old with
