Does he know I like him?

Okay so theres this guy ive liked for a while now and his name is jessie. Hes pretty shy, but hes popular. Hes in my art class. I have only told like 5 people i like him, but i dont really think they would tell him. Okay so yesterday, i noticed that he was staring at me. Not all the time, but i saw him glancing. I almost, actually, got him full of paper mach� glue (oops :O) cuz i bumped into him. But i didnt. I thought i was just imagining him looking at me, but today he was doing it, too. And more often, actually. I would see him gaze over sometimes. In art, we were paper mach�ing (idk if thats how u say it) and i had extra newspaper. So i noticed he was like behind me washing his hands (where i sit). I got up and went the LEFT way to put them away, and when i turned around i realized that he was standing on the RIGHT side of the sinks.Standig there staring at me! When i went to my seat then he started walking towards the other side of the room. In gym he also stared at me when i walked by and when was walking out of the cafeteria he was too. Do u think he knows? Because i tried not to make it obvious... :/ oh god he probably thinks im a freak now :(
