Advice on situation with girl in my class..?

I've known a girl in my university class since November. I initially started sitting beside her in class. We would also talk and chill during class breaks. After awhile, she added me to msn and facebook. Sometimes we would chat on msn. Oneday, I persuaded her to come along to a University pub crawl. She had a great time. After a few weeks, she gave me a facebook message and said ';Hey. wanna party tonight';. She invited me to her place, we started drinking with a few of her friends, and went to the club. Then in December, we went to the University bar and club with a few friends. While dancing she would look in my eyes at times during songs and say ';Hey. Wanna go to the other room and dance. It's too crowded.'; We danced in the other room and had a great time. During the holidays, I gave her a Happy New Year facebook message and she responded. She called me when I got back in town for University. She basically was curious about my holidays, and was wondering when I was going to return to classes. Just recently in class, I saw her the other day. Initially she said “Hey. Sorry I didn’t tell you when classes started.” I had missed a few lectures. I told her to not sweat about it. We then started talking about our holidays. I must admit that it took me a while to get re-acquainted with her since we hadn’t seen eachother for more than a month. Then during break, she was talking with her girlfriends about the law prom ball. She directly asked me “ Hey. Wanna go to the law prom ball.” I agreed. Any advice on this situation.Advice on situation with girl in my class..?
Just stay cool about it because if she See's that your kind of nervous because you like her then she'll get nervous and it'll be all awkward....but i think your doing pretty good just be you!Advice on situation with girl in my class..?
Has she told you that shes Gay at all? Or maybe Bi? If your either one and she is and you two odviously have a blast around one another why not go with her? Whats bad can come of it unless your not gay or Bi???
She is obviously a vampire and will kill you without hesitation, Dr. Khans advice is get checked for homosexuality because no real guy would post girl troubles on the internet.
I don't understand the problem.
