I pretty much agree with Lefty, not that Hope is wrong either.  Hers is a more direct question and of course you will get your answer up front and you'll know what is going on.  But there are a lot of shy people out there that can't just go up to the person they like and ask them that question, I know, I'm one of them. 

I was pretty much in the same situation as our confused friend asking the question, actually I still am.  But being a guy who has done what the guy has done to her, by playing around with her and trying to get as close as possible to the girl, there is only one of two things that I think is going on. 

He can probably be a player (only if he does this with other girls too), but my most positive guess is that he really likes you, because I know, I've done it many times.  But I never knew what "she" was thinking because she never "really" showed any signs of liking me.  So things did not work out (for me actually)

So what I have to say to our dear confused young lady asking the question.  If he continues to do this, and if you like him, respond back with the same body language he is sending you.  And then after this has gone on for a while, you (or him) will have to take the major step of asking the other if you like me, or if you want to go steady? You know what I'm saying. 

I reacted to this question because it has happened to me many times with most times breaking my heart because the other one did not respond to the feelings that the other one was giving.
