Guys, what do you think?

Okay so there is this guy in my math class that all of a sudden is now staring at me. Its started about three weeks ago when I was on a class field trip. H e was sitting behind me and when I looked back I caught him staring at the backof my head and then he saw me looking at him and then looked away. Then this past week he knoe that I walk down a certain hallway and he turns in that direction and stares at me when I walk past and then when I look over his eyes shoot down to the floor but asI pass he starts too turn to watchh me walk by. In lunch he sits a few tables away from me and he doesnt usually do this but now he goes over to the table in front of mine to talk to him and tries to casually turn and glance over. when he left he glanced at my table but then came back around. And then I had to leave and he watched me walk out. I don't want to get my hopes up for no reason because I kinda like him too. so what do you think?
