I'll still standby my "2 month theory," if you've been talking to her that long you will probably be a friend forever and not too much more. For your sake, hope I'm wrong, and it's happened before that you go longer and things turn around.
Does she touch you at all? Like out of the blue while talking she touches your arm? How did you get her #? If she gave it to you (not you give yours to her), she WANTS you to call her for some reason- can you guess why?
Whatever she likes to do, say shoot pool, say you and some friends are going out to shoot some pool and invite her. At the last minute say they all backed out, but ask if she would still like to go out and play some or perhaps do something else. If she says yes, she likes you- may not want to get in your pants, but over the net....somebody can only do so much for you!
