Hey, 19 year old guy in a 10 month relationship with an 18 year old girl. Before I started dating this girl, I had not done anything besides makeout with a girl. She had two previous boyfriends, one of which she had done most everything but sex with. A few months into my relationship, I found out in between her and my ex, she hooked up with my best friend and I never knew about this. It killed me. Even though it was before I was even in the picture, knowing this truth has hurt me to this day. I've been coping with it for a half year now and it sucks. The problem is, I love this girl so much and we have such a good dynamic and everything feels right except I can't forget her past. I feel if I had some sort of sexual history it wouldn't hurt as bad. I always picture her and my former best friend together and it just burns a hole in me. My girlfriend and I lost our virginity to each other and our sexual life is amazing. Why is this bugging me so much? I love this girl and I don't want to let her go, but how do I forget her past?
