Do you think this girl likes me?

I met this girl at school about 4 months ago. At first I liked her and asked if she ever wanted to hangout and she said sure but I could tell she said yes to just to be nice. It never happened. Weeks later she tells me Im not the guy she thought I was, and Im different from alot of other guys. And there are not alot of guys like me. And we started hanging out away from school for the first time. Now we are really close, we both have alot in common and I can tell she feels comfortable around me. Today I picked her up from her house and we got together with a few of our classmates. When I took her back home usually she just gets out but now she asked if I wanted to come in her house and if I wanted something to eat I said sure. I feel she has shown signs that she likes me, the way she compliments me all the time, and she tells me things she wouldnt tell others. She hugs me everytime I say bye to her, and one time layed on my shoulder during one of our classes. We text eachother all the time, and sometimes when we hangout it feels like a date.The only problem is she has a bf who goes to school far away and they hardly ever see each other. I met him once. She told me sometimes she feels like they are not bf and gf more just friends. And there have been times where I have been with her and her bf made a big deal about it and she just hung up on him or didnt answer her phone. I do like her and I think she likes me, but since she is in a relationship I feel I shouldnt say anything. Its just tough to keep waiting. Should I just wait it out and continue to just be friends with her and see what happens.
