Don't know what to do with this girl?

Ok so I've been kind of sort of talking to this girl for the past month or so and I'm in a jam. I feel like she doesn't like me but we've been talking everynight. We've hung out a few times with groups but not as one on one. I want to hang out with this girl one on one but I don't know how smooth it would go. He best friend claims that she likes me but I just don't see it. I feel like if I keep on talking to her via phone shell get sick of me and drop me. I'm really starting to like this girl though. Ahhhhh what should I do? Somebody help please
