Does he like me? Please please help me out?

Long as I remember, this guy has been going to my church but we've never really talked. He's more on the jock side but tends to be quiet and doesn't reach out to many people. I rarely ever see him with girls. But this past week while we were at camp then we started talking which really took me by surprise because I figured he was out of my league. We played a couple games of ping pong which got us talking. For the next 4 days we'd talk each day a couple times. I was catching him looking at me from time to time. He is pretty shy from what I know and yet last night I was sitting down in church and he walk over and asked me if the seat beside me was taken. Right before that he was sittin with his mom and brother. So to me it sounds like that took an effort for him. He'll tease me about my lack of steady rythym when clapping haha, and he seems like an all-around great guy. It's crazy to think he'd ever like me, but the only thing that keeps me from beleiving that he does is that when I see him then he'll usually be textin someone..I don't know if it's a girl that he likes or what, so I'm trying to not get my hopes up. He's turning a senior this fall. Please help me out, because honestly I don't know how to take this. Thank y'all, it's greatly appreciated!
