I'm really confused by this guy?

[Alyssa]

I really like this guy in my p.e. class and I always catch him looking at me. I friend requested him 2 days ago in facebook and an hour after he accepted it he started a conversation with me.

Him: hey hows it going
Me: hi
Him: what's up
Me: nothing really. You?
Him: I'm pretty dam good
Me: that's cool(:
Him: I never really get a chance to talk to you in person
Me: yeah I know. Then talk to me?
*he didn't reply back*

He never talked to me at school. He only stared at me like always. Then he started another conversation with me on facebook yesterday.

Him:hey how's it going again
Me: how come you only talk to me on facebook
Him: I don't know
Me: haha okay..?
Him: so what do you want to talk about
Me: I don't know. You go first?
Him: na you go first
me: I don't know what to talk about. Do you like sports?
*never replied back *

This morning he messaged me good morning. I didn't reply back.

Does it sound like he likes me or is he just messing with me?
