What does it mean when he slaps my butt and he has a girlfriend?

There's this guy Jake, who's my friend, he's friends with this guy I kinda like who's also my friend and that's how we met. We all talk and we kid around, but one day about three months ago he started slapping my butt I got really mad and slapped his face. then he slapped my butt again I got mad again, then I was hanging with him and his friends and Jake stole my wallet and saw a pic of me that I took, and he took the pic when I didn't notice and he passed it around to his friends and looked at it. most of the guys said I'm cute, hot or attractive, one guy I'm friends with in the group kissed the pic.. and Jake looked at the pic while I was fighting to get it back and that I was cute. three months have gone by and he still slaps my butt hard when he gets the chance and when his Gf's not around. He acts like it's no big deal, He's a friend but why does he do this? He has a girlfriend who is in grade eleven who he seems happy with, I don't like him at all...HELP!

You need to tell him to knock it off or else you can no longer be friends with him. His behavior is totally inappropriate. At your age, many boys act that way, but it doesn't mean you can't call them out on it. He probably likes you as more than a friend, or at least thinks your behind is fun to play with. Either way, it still isn't appropriate. Talk with him. If he doesn't take you seriously, avoid spending future time together.
