Does he like me or is he just messing around?

I guess he is just playing. It doesn't mean he wants to be nasty and hurt you. Maybe he is flattered that you like him, it's new for him, he enjoys it, but at the same time he knows that playing with fire is safe, because he won't burn HIS fingers.
But honestly, I wouldn't mind and try to keep it on friendly level. If he makes you smile, what can be wrong with that?
I was told that some have crush on priests - just because "it's not gonna happen." Maybe he feels a bit similar.

But from what you have told us, I don't think he means any harm and he I think he wants to be a friend with you. Just don't fall in love.
