Alright so theres this girl that I've been crushin on pretty hard for the past while. But I've already heard from her friends that shes not interested in a boyfriend (Figures

). Anyways, one of the first times we chilled we hit it off pretty good and all that but last night her (we'll call A), her friend (S) and then a couple of buddies and myself went out to a nearby bar. We're there drinkin and all that and there's this one guy hitting on her who shes known from the past and she cops out and goes and chills with him for awhile. Everyone was pretty surprised by this, as its not exactly the most polite thing you can do while goin out with friends.
So I mean, I guess it was obvious that I was choked because she asked me why I was pissed off at her. So we all leave the bar, drive to my place (keep in mind all of us are pretty drank) and hang out for a bit. Then I decide that Im just goin to drive S and A home. After dropping off S, A says we need to talk. Turns out one of my buddies I was with told her that I liked her a lot and all that jazz. So fuck it, I admit straight up and she comes back at me with "But you don't act like you like me at all blah blah blah You seem to be closer with S?"
WTF! I don't know what the hell to do, the conversation didn't really get me anywhere except to find out that yes, she doesn't want a boyfriend. But we chatted about a lot of things and she opened up a lot to me. On the other hand, I asked her to kiss me (I know, i should have just kissed her) and she said no. Whack.
Anyways, any advice is much appreciated.
