my gf has had a rather promiscuous past in college. shes about done with school, i'm still in school but we both trasnferred. we've been together for a year now but in any case, shes had a reputation as easy and everything and i have this terrible self-defeating personality which doesnt help at all. for example, if i hear a really crappy annoying song, instead of being able to forget it, i'll be shouting it over and over in my head while at the same time im like fuck i hate that fucking song! so lately when we fuck im thinking "i wonder if this is how she looked when god knows how many other guys fucked her." her ex is in town for a court date and is staying for a week just cuz he can. they're more friends than they are ex's but hes staying at her apartment and shes staying with me. i had to go over to her place once to get some shit and i ran into him on the train and so we were stuck talking for like 20 minutes and i kept thinking about how he was probably thinking how he fucked MY girl. i dunno what to do about this. i love her a lot, but this is really a problem for me...and its not like shes doing something that she can change and it'll be all better. the only way it will go away is if i do something about it. but what does that say about my relationship with her. even though this is not a normal thing, does it mean i need to keep looking? everyone has their past i know, but it's starting to get bad, it really gets to me when im at work and at school. any advice?
