Does he like me or is it my head?

I have a crush on this guy, a year older than me, and I've known him all my life. At school he always is subtly trying to get my attention (it seems) and looking my way like he wants to talk to me. He laughs to himself at the funny things I've done, but we don't have a regular conversation. He seems to want ot make a move, in my mind he does. One I looked ta the seating chart for his period in French and found his desk and on it it was engraved I <3 G. My name is Gaby. But somebody else could have written that. Are all these hints in my head and im making things up r does he like me? Please tell me what you think!
