WHY DOES HE LOOK AT ME!?

Its really weird because I keep marking how many times this person keeps looking at me during class. I mean yeah Ive heard he likes me and yeah we've slowdanced 6 times at the valentines dance and all..But...Does he like me? We were watching Space Chimps for french class to end our unit of space and when I laughed he'd look at me STRIGHT in the eye and as soon as I look hed quickly turn away. When I try to mouth words to my friend which sits at the back, and he sits behind me while I'm talking to her my eye catches him looking at me. He flutters and looks down at his paper..Is this a sign he likes me?
