Do you think this guy likes me?

I just met him last year, and I guess you could say we are close.

Everyone kids around with us saying that we are going to get married, and we both usually just laugh and shake our heads.

We are good friends, and we hang out. It just feels natural for us to be together. He's never insinuated feelings for me though.

He'll comment on what I'm wearing, or tease me a lot. He changes from day to day.

What should I think of this?
