Why does he push me away?

He *might* be creating space for you to move into - ie, stimulating positives by showing negatives.
Think of it like a waltz - if your partner moves their foot back, creating a space, the natural is to move into that space.

His deal is he doesn't want a girl to be affectionate back to him as he may be embarrassed about it. If he's around his friends that may be why he does it. If he just does maybe he's not in the mood. Just what he does to you just do it back to him. If he says what's wrong be like that's what you do to me so how you like it? Make him realize he's wrong for doing it

I don't want to sound like an ass but does he act "odd" (meaning stand offish) while in public, and only shows this "affection" to you while alone? Does he tell you that "you're special" and compliments you ALL the time, all the while marveling how much he likes you even though you are not his "type"? Are these " " getting on your nerves?

Sounds like to me he has a problem. The reason he could be doing this because he fells like he can do it to you,but he does not want you all over him. Because he may not want people in school to think you both are together. You might want to talk to him and ask him, why is it ok for him to hold your hand in front of everyone, but when I do it you push me away. Or you should push him away when he tries to pick you up or hold your hand. Then if he gets mad and askes you why you are acting funny. Then tell him that this is how you treat me when I do the same thing to you,now you know how I feel , when you do it to me. You should talk to him and ask him what is his problem. He acts like he is asham to let you touch up on him, but not the same when he does you. I hope this helps you.

He just not that into you if a guys really likes you, he'd be finding news ways to touch you, not you working on touching him, but him trying to touch you!!!!
