If he does indeed like me, how do I tell him to get lost?

Ok so there is this guy at school and we don’t really talk. But at the end of last year things between us got a bit weird.

One day in a free period at school, we were talking about why I wanted a ring for my wedding ring finger. I didn’t even explain it to him and my other friend at all and he knew exactly, in detail might I add, why I wanted one and what it was for.

That was weird, so I figured ok whatever thats fine. Next free period we shared together I was kind of weirded out by the fact that he was touching my arm and hand and telling me I have really nice eyes. It was weird. Very weird.

A few months later, the behavior is more suggestive that it is explicit. He listens in on my conversations and whenever he says something he always looks to me to see how I am reacting. I spoke to one of my good friends who told me he was gay.

Maybe I am reading too much into this. Maybe I am over reacting. But seriously, if he does indeed like me, how the hell do I tell him to get lost?
