First off I'm more about inner game and serious relationships, not a fan of the old school pickup scene and banging thousands of chicks, faking it and canned material, not that it probably matters but anyway. Now that thats done:

I'm a 22 y/o AFC. I was just good friends with this girl for a few years and then things changed and we made out. She has more experience than me but we're both still virgins, she was the first girl I properly made out with. Things between us are going further fast but shes moving out of the country soon for good (not her own choice). Shes attracted to me and is butter in my hands, but she knows and said this is just a little fling (I should be thinking the same), but I can't help but attach feelings to this girl, we get on so well, we're so similar in life, nature and aspirations, I would totally be in a LTR if she was staying. I can see she's a genuine girl of great value. But she's got her mind set on moving on, the feelings not really mutual but I think she's restricting and stopping herself from feeling attached because she knows shes leaving. We've joked about me coming with her but at the end of the day I think she is more resigned to the fact than me. This is a battle of logic and emotion and its killing me, being the AFC that I am and her being my first.

How do I stop being a little bitch and just make the most of the experience for what it is? What if I fuck this girl and get even more attached? Logic says just get the experience, but I can feel the oneitis is creeping in HARD, do I hold out longer for someone more stable? You're probably going to tell me go out and approach other girls and get over it, but I'm not actively approaching any girls, I'm not the most social outgoing guy by nature, this girl just seemed to land in my lap.

EDIT: The ball is rolling gents, I'm approaching others now, thanks a lot
