Advice

I just realized that I love my boyfriend. I am a virgin, but he has had sex with two other people. It really hurts me to think that he has given himself away to two girls before, but since I love him, I know that I should try and forget about it. It's just hard to know that he's had these types of feelings for others before and made love to other girls, and that I am inexperienced and don't understand as much as he does about it. It's hard and I'm sad and would like some advice on what to do.
