Does he ...... Maybe not?

Ok there's this guy that I really like. His name is Grant, and the only cl I have with him is Homeroom. So two days ago I was at lunch, and he was sitting at a table catercorner to us and he was facing me, but not enough so he had to turn his head slightly every time and I caught him looking at me a couple times. It was weird because he was surrounded by really popular girls. So anyway, we were in homeroom yesterday and he kept looking at me, and of course I was looking at him, and i caught him several times. What does this mean, that he likes me or does he just want to stare at my face or something ??? :)
