Ok, in the past five months or so I have become aware that I have a horrible issue with relationships in general, which is affecting my current relationship in a very bad way. Whenever I go see my girlfriend, or talk to her on the phone, or pick her up for the weekend, or ANYTHING AT ALL that might be somehow related to her past relationships, I constantly remember what I have heard/know about her ex-boyfriends and waht they did togehter, and I feel really hurt about it, and that projects onto our mood, etc. and just affects us both horribly. For example, if I am going to pick her up on a school night, I for some reason cannot help but think about the fact that one of her ex-boyfriends would have gone over and they would have had sex and enjoyed each other, etc, and it just makes me want to throw up, etc. etc. I feel as if I am missing something or some concept that everyone else on the planet sees/feels. I see people who have remarried with children and have stepsons and daughters and I just can't honestly see myself in that sort of relationship wihtout feeling some extreme emotional pain everytime I think about them and their past. Like sometimes I feel like every other human being on the planet is blessed with the ability to just completely ignore the past or something. I just feel like if I wasn't around, my girlfriend would find someone else who makes her just as happy as I do, and therefore I am really not that significant and there is no reason for me to feel very special in her life. I hope that I am just being naive and somehow I can come to a revelation in this respect so that I can move on with this issue and have a healthy, happy relationship but at the moment I am just afraid that it is something that I will never be comfortable with. Has anyone else ever gone through this or had any experience with this problem and could tell me some things that might help me through it? I feel horrible because everytime I get upset I just ruin our night and I desperately want to figure out something to do about it. Sorry for the long post, and any advice is greatly and desperately appreciated.
