Flirting

What to do when the girl you like hooks up with another guy at a party?

This year in school I've started to jump up the social ladder (kinda why I hate high school) and started being "cool" enough to start going to more parties. Anyways the girl I've liked for a really long time showed up, I'm pretty sure she likes me too because every time we talk it just turns into a flirty conversation. At the beginning we started talking and she got a little touchy (she got drunk a little fast-before I did). I planned to talk to her later that night, but went to get some more liquid courage to find her hooking up with one of the nastier guys there. Already in a happy place I didn't really care even though one of her best friends asked me if she should break them up, and I said "let her deal with it in the morning" (dumb move). Later that night I saw them making out on the stairs when she grabbed me and started telling me how cute I was and how she really likes me while she was grabbing me and trying to kiss me with the other guy standing right there (who happens to be a mutual friend). I pushed her away and it all started to sink in and hit me and I started to feel pretty bad. I saw her the next day and she asked me if I still think the same of her and I told her: "that stuff happens and you just have to move on". She gave me a giant hug and started hitting on me again, not wanting to do deal with this at that moment I told I had plans and had to get going.

I've had my heart broken in the past from relationships and now I'm left a little confused. I'm done with those kind girls and now I'm looking for a real relationship (lol I'm a hopeful romantic). Under ordinary circumstances I would not give this girl anymore thought, but this just happens to be the girl that I've had a crush on all through high school
