What is happening to me...do i really like this girl?? i think she knows but she wont talk about it so wtf!?

You care about her, and you're a respectful guy that wants a relationship with her. Just know that if you get into a relationship with her, she's going to be doing things with guys when she's drunk when you're not around. You're dealing with a really immature and sorry... slutty... girl. I'd find a nice girl, it will help you out a lot. If this is truly the girl of your dreams, then your dreams must involve your girlfriend slutting it up with everyone else. :(
