I'm thirteen years old and I like this guy in my class who is a year older than me.he is a funny and very handsome boy and we are like cool friends.he occasionally likes to hug me and lift me (like how a bride carries a groom) and I find myself laughing at all his jokes (even though it isn't funny ) the problem is he is a flirt and the stuff he does wit me he also does it to my other friends :confused: so I don't think that he is trying to say I'm interested in you because he does that with every girl ,what should I do.

I think he is just being himself and enjoying it. Be his friend and enjoy it.
Often when people decide to be boyfriend/girlfriend, then they break up
Often they never have that closeness they once had. Sometimes they even end up hating each other. So enjoy having a really great friend and if it grows into more then great.
If not then you have a good friend.

He is just testing you to see if you care or not

Even you like him,but be cool,tell him you are special,and you don't like the way he treats you like treating other girls!
