I cant tell if she is really intrested in me

Im almost two years out of a horrible relationship. I met a girl in school about 2 months ago. She seems intrested in me, I mean she exhibits some of the tell tale signs. Last week we actually met at a club outside of class and she made the first physical contact of our relationship, It was just a hug, But it was something. She also has asked me twice the dread question.."What are you thinking about?". I really enjoy spending time with her in class and during breaks, But I wish it could be more then just an hr a day. Any help would be appricated.

well if i were you i'd just ask her if she wants to do something, rent a movie, go out and eat or something.
