[Sin Secret]

Hey there.

It seems you've run into a silly problem that many guys seem stuck on. My up-straight and honest (opinionated) answer is Get over it. It sounds harsh, but really, I think thats the best thing you can do for yourself and your girlfriend.

She had sex with someone else, so what? If you break up, and you find someone else, you'll have had sex with someone before your new girl. Sounds confusing, but the point is that sex happens. You (She) can't hold on to virginity for every new like/love you run into, it doesn't work that way. She's already expressed that you're far better than him, so acknowledge that you've got her now and he does not matter.

There's no reason for you to feel jealous whatsoever. If you really like it, it shouldn't matter who she had sex with before you, whether its the jerk you knew or six guys from around the block. It's not really your business. Just like if you weren't a virgin, it wouldn't be any of her business who you'd slept with.

But after being honest and (possibly) a bit rude, here's what I think would help you.

Try reminding yourself that she was a different person before, and that she probably had her reasons for being with that guy, and sleeping with him. Remind yourself that after her (whenever that may be), you will be with other girls, and those girls will have been with other guys (or girls).
The biggest thing is to remind yourself that she's with you, not him. She's chosen you, which means she likes you better. Maybe that preference is because of your personality, looks, or sexual abilities, but regardless of why, she chose you. That's important. He doesn't matter because she doesn't want him anymore, she want's you.

Your not hopeless, you just have to figure it out in your own head. It's the past, it can't be helped or changed; he doesn't matter, the two of you do.
If you dwell on this situation it'll only hurt you, her, and your relationship. .

Good luck,
