Does this girl I've know for a couple of weeks like me?

We are both freshmen in college and we live in the same dorm complex, we have a few mutual friends and that's how I know her. I can not read her because she is so quite and sometimes shy. The other day we were walking through the dorms and we got on the elevator, it was her me and a few of are friends, she leaned her back against my chest the whole ride, now this would normally be nothing, just a result of to many people on the elevator but she had three feet of wide open space in front of her. When we got to my floor she stayed with me and another friend of mine and talked for a couple of hours and watched tv, she said she would leave but are couches were to comfortable(they really are the greatest couches I've ever sat on) She makes eye contact with me a lot as well. The next day she had some gay dude in her room(I don't know if he for a fact is gay but talking about having sex with Brad Pitt doesn't tip the hetero scales in your favor) but I know for a fact she is single. i don't know maybe I am just over analyzing things we've only know each other for a couple of weeks. What do you think?
