I feel like I’m not the type of person to be able to handle my partner looking at someone else in a sexual or romantic way. I was left for someone else in a relationship that I didn’t even care about and it has made me fear it even more because the person was their friend. she has reassured me about how she’s not like that, she wouldn’t do it, I should trust her etc and even got upset that I was acting like I don’t trust her. and now it’s all of a sudden I should be ok with her talking about something like that because she didn’t plan to do it without me, she just wanted to try it or something along those lines. I don’t know how to deal with it because she made me feel like I had just been paranoid for 4 years and that it wouldn’t possibly happen, and now she thinks I’m being mean about it by feeling heartbroken and betrayed
