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?

He is interested in you. May be he is scared to talk in person or may be he is scared talking to girls... he want to talk to you online but don't find any interesting topic to talk and don't want you to think he is boring or so

probably he is shy or lost interest. make him laugh. try to loosen up first.
