I have been with my husband since we were 17/18, and we got married a year and a half ago. I have never had sex with anyone else, in fact, the farthest I've ever gone with anyone else is kissing. My husband, on the other hand, lost his virginity when he was 15, and has been with several other girls (a couple of them, I was friends with). I know that all of these things happened before we were together, and he can't undo anything he's already done, but I'm extremely jealous of these other girls.

I feel like such a bad wife, that I can't just forget about this. He didn't do it to hurt me, and I don't think he would ever intentionally do anything to hurt me.

How can I stop thinking about this?
