Hi, so this is my first post here and hopefully someone can help.
I've been dating my girlfriend for a couple months now and we like each other a lot. She is 19 and a virgin, and I'm 22. However she has a psychological issue. She can't handle if her boyfriend had sex with other girls before. She says that she has to feel special to the guy and doesn't want to be "just another girl". She says that she also can't handle imagining the guy actually having sex with someone else, even if it's in the past. She feels like some other girl "already had him" and he's "used". She also doesn't want to know that some other girl experienced anything like that with him. She hates feeling like that but doesn't know how to fix it.
She never had a long relationship or been in love before and says that this ruined previous relationships. She also says that even knowing about exes of the guy she's dating can turn her off immediately. She says she wants to get cured from this bad feeling. I think that maybe it's a reflection of some belief she subconsciously has, but the belief must be ex "going too far" . I appreciate anyone's help on this as KI'm not sure how to fix that.
