Does my guy friend like me or is he just having fun?

Yeah girly, he likes you. In keeping of typical guy fashion, he's very shy about coming straight out and telling you that he likes you, so he's gona be rather coy and play games. You might have to be the one-actually you WILL be the one-to take the initiative here, but he definitely likes you! Go ahead, ask him out, and when he says he's been wanting to go out with you "for like a year now!", you'll be so glad that you did!
