I'm falling for my best friend?

I'm 14 and gay, not out to any one I'm DEFIANTLY not ready to come out I think I'm falling for my best friend, I've know him since we were 7 he lives just down the road. I have no idea if he's gay I don't think he is he hasn't had a girl friend in a wile. I have very strong feelings for him. I can't help but stare at him and I know I'm acting weird around him and If I keep it up he's going to find out but I can't help it. I can't exactly avoid him because were best friends, I know he doesn't have any thing against gay's his cousins gay and there close. I defiantly can't tell him I like him, I'm worried it will damage our friend ship and I can't lose him he's my best friend. WHAT DO I DO????
