Why does she treat me differently from her other guy friends?

[Anonymous]

So I have fallen for this girl I just became friends with this year. We get along really well but I think she just sees me as a friend though. What I don't understand is why she treats me different from her other guy friends. She is one of those girls that has a lot of guy friends and likes being "one of the guys". With them she is real casual and all buddy buddy. With me she is more awkward but in a cute way though. For example, our conversations usually start off weird like "sooo...how was your day" kind of thing, but then end up going into a joking playful argument.

Now usually you would think that's a good sign but I'm not sure. It makes me wonder if she can tell I like her as more than a friend so she just acts different. I don't even know what I'm asking really. I just don't want to mess this up.

She sounds a lot like me. I have a good many guy friends and can be totally myself with them. But there is this one guy I Really like, and I'm a little awkward with. We talk on the phone and its fine, it's just something about being around him makes me nervous (its because I like him) Yeah I think she definitely likes you! :)
