This is so overdone, but....there is a guy. duh. help me out here people.?

I have this friend. His name is John. John is my best guy friend. As you can probably tell, I have this crazy kinda crush on him. We used to be really close at the beginning of the school year, and we see

at least once every school day. At my lunch table it's all really fun and we meet before school sometimes. A lot of the time, he walks up to me and puts his arm around me casually. We flirt, and it seems like he likes me, but I flirt with this other guy too, just because I don't want to let him know that I like him...because that would ruin our friendship if he didn't like me. We were becoming closer and closer and I thought he would ask me out but randomly he's been acting a little bit distant. Help?
