My friend is being distant, can someone help me?

[Shain B]

me and my friend met when we were in kindergarten, and have been BFFs ever since. (im gonna be a freshman this year). Anyway, ever since i moved to a different town, like 26 miles away, she has changed. Before i moved she was a little like a tomboy, like me. And now, she talkes about wearing thongs and guys and this stuff. I know that she is just growing up but, and she doesn't think that there is anything wrong. But she seems to have other friends. I just don't know what to do.
