Hey dude, welcome to TFP
Now, firstly, you think too much. But that's ok, so do I.
I think while you two are living so far apart, you should put the idea out of your head of anything happening, otherwise you're just going to end up torturing yourself, and that's really no fun. Life's to short to be miserable.
It's hard to comment without really knowing much about this girl. But, accept the fact that you're both quite young (and I'm really not trying to be condescending) and what either of you want can shift on a dime.
I don't think she was on purposely trying to play with your head. You guys shared an experience, and at the end of the day, your friendship and the way she sees you will greatly impact what further things could have happened. It doesn't mean she doesn't care or like you, or want to fuck your brains out. But honestly man, we wont have any answers for you. You have to communicate with her to find all that out :-)
So as far as what you do goes, communicate with her. If it's something that is bothering you, talk to her. You might not want to hear what she has to say but at least you'll know where you stand.
Oh, and having feelings and emotions doesn't make you a fag, it just makes you human.
All the best mate
