I dont understand him...? (advice)?

he has no problem flirting with other girls or talking with them but with me he'll talk to me a few times if im lucky (we see each other everyday) and its usually him teasing me with that smirk on his face. sometimes he'll look at me or his friends will but there are other times when i see him just looking around at almost everytime in homeroom. usually when hes talking to other girls he doesnt smile that much (but then again...) idk is it possible he might like me?
