^^That's pretty much it^^
If you know this girl is definatly going for you more than her boyfriend, then maybe you should make a move, to further the relationship. Just don't get the boyfriend mad. I'm not sure how to do this; you can just ask her to a movie sometime if she seems into you. Please tell more information, so we can help more
