So let me try and make this as short as I can.

My best friend that I go to school with has a girlfriend and I am absolutely in love with this boy. He hardly even talks about her and all he does do when he hangs out with her is purely have sex. I know him and his girlfriend are not connected on an emotional level. He flirts with me and the things he does to me is not something someone just does to friends. Him and I have so much in common and we get a long so well.

He always initiates talking to me and texting. He plays around with me, we play fight and do things that would be odd for someone who just thinks of me as a friend. He is a very touchy and close-to-you kind of person. It always seems like he wants to try something or say something to me in person but then he doesn't. 

Some days he'll be really flirty, I'm talkin super touchy and in my face. Then the next day it almost seems like he's mad at me and will have kind of a grumpy attitude. A specific incident would have been when we were at a book store together with another friend of mine, and he pulled me away from my other friend and dragged me across the store in a playful manner almost holding my sides and when he stopped he was acting nervous like he was trying to say something but then he stopped when my friend had come back. The next day at school He was being almost rude to me and was kind of giving me the cold shoulder.

 I've been alone with him a few times after that and he hasn't really tried anything. Just so confusing for me, the way he looks into my eyes. I can't say anything to him about my feelings for him because if he doesn't have any feelings that way for me it would completely ruin our friendship together and with our other mutual friends.

I've been seriously infatuated with him for over six months now and I'm very stuck and I don't know what to do.
