Why does he sometimes look surprised to see me?

Anonymous
I used to like this guy at school and he found out that I liked him last year. This school year sometimes he looks surprised to see me in the hallways, his facial expression changes. He shouldn't be, we do go to the same school lol. Also, sometimes when I end up behind him he looks back to check if it's me and looks directly into my eyes. I absolutely know he doesn't like me. Is he paranoid or something? Dose my presence bother him? I hope I don't scare the poor guy or anything.

I don't like him anymore by the way, but I'm not sure if he realizes that or not.
