Do you think he might like me? ?

This kid from my school had been friends with me on facebook, for a while before we ever really talked. Well I finally met him in person and we started to talk on facebook and when he saw me in the halls. He messages me on facebook and likes all my status' but now he ignores me in school. The other day I was talking to my friends at their lockers before homeroom and he kind of was flirting with me, like he was touching my arm and sort of pushed me away as like a joke, but now he hasn't replied to my facebook message, He uses alot of smilies too. But I don't know, he seems to talk to alot of girls, and he hugs some of his closer girl-friends.. What do you think!
