<human>: Provide a brief overview of the text.

I know, another brilliantly ambiguous college relationship. A girl in my apartment building has had a crush on me for awhile. I decided to see where things went this semester and we had a relationship where we hooked up, slept over (did everything but sex), and went on a few dates. I got somewhat attached, but we were both a little confused and I got mono and things cooled down for the last couple of weeks we've barely talked.

I've always known she's a bit unstable and drinks a bit too much too quickly, but she really surprised me this weekend. I'm about to celebrate the 21st birthday of a mutual friend when she shows up at the bar hammered and immediately is all over me. I'm a little freaked out and try to communicate to her that I want to focus on having the first birthday shot with our friend, and end up just walking away for a moment to clear my head (I'm still really attracted to her) and find my friend. 

Anyway, she takes this as a total rejection and disappears, sending a few not totally coherent texts. I respond that I want to focus on my friend's birthday, I want to talk later, and said she can come hang out if she behaves (admittedly bad phrasing). The next morning she texts me, angrily telling me that she cried all night and ruined her weekend, etc. I try to explain the situation, but apparently fail.

At this point, I want to either end things entirely or at least set some solid boundaries (there is definitely no chance at any real relationship at this point, we simply don't have enough in common and she is too unstable), but ultimately I just want us to see each other in a positive light. Is that a vain hope? I'm really obsessing over it right now and it's distracting me from my work.

Has anyone had a similar experience?
