Why would a guy stare at you all the time but act aloof around you?

Anonymous
He stares at me all the time only when I'm not looking (my friends have caught him doing this several times) and looks away quickly if I catch him. But whenever he's close to me, he acts very aloof and pretends like I don't even exist. He also gets very quiet around me.
