Why would a guy do this????

Question

What would be the reason that a guy (he is 17 years old) would keep glancing at me in class but never talk to me?

also, whenever he sees me he just stares at me. but he doesn't talk to me and we only talked once last year for a project. this eyecontact stuff has been going on for OVER a year now.also when he looks at me i ignore the glance or pretend i don't see b/c i suck when it comes to guys. i really like him though.

also once when i was walking out of class and he saw me behind him he improved his posture and stood up straighter.would that be a sign he likes me or am i analyzing too much?

he is not shy with his friends he is really outgoing when he is around them and he asks lots of questions in class.

last week i was walking up a flight of outdoor stairs. there is a bench on the lower level that you can see when walking up the stairs. i looked down at the bench and there he was. he was biting his nails and looking directly at me. we held eyecontact for 2-3 seconds.

Answer 1

Next time that your eyes meet...   smile..

Answer 2

he likes you, but doesn't know how to express it other than staring.

he'll mature and come to his senses and talk to you :]

Answer 3

I think he likes you and is trying to see if you give him eyes back.  Guys can be shy too and worry about rejection.  Or maybe he thinks you are pretty and cant take his eyes off you.
