Is there anyone else out there who also finds is so fucking difficult to let go of your partner's past? I really feel like that's the only thing that's stopping me from leading a really happy life with my boyfriend. I've come so far in overcoming my issues and working on myself. I don't even feel like I qualify for BPD anymore. My mood swings are under control, my depression and anxiety are pretty much gone, and my self-esteem has improved a lot.

 The one thing I just cannot get over, and the one thing preventing me from moving forward, is the fact that my boyfriend has had long-term relationships before me. It makes me feel inferior and I compare myself constantly to his exes (especially his last one because he was with her for 5 years). I worry constantly that he doesn't find me as beautiful as his exes or other girls, that their sex was better than our sex, that they had more in common than we do, that they had more fun and special moments, and most of all - that he loved them more than he loves me. 

I understand this is just my BPD, but how the fuck do I get over this? It's really impacting my life and I feel that if I can't overcome these obsessive thoughts, I may ruin our relationship. I'm jealous over girls in his past which is so stupid because he didn't even know me back then. 

Help.
