I like this guy but he is confusing me a lot?

So the thing is I really like this guy and we aren’t this close. But he is weird with me. He picks on me all the time but whenever I look at him he smiles and looks down, like he can’t handle the eye contact. Then I see him staring at me from across the room but he plus it cool. He looks either annoyed by my presence or attracted by me. I don’t knowwwww
