@Aya dh ,
Maybe people didn't see your other post, I always think it's best to add to the original post to get some attention but anyway....
So it's been two weeks now, why are you feeling the same and a teacher slapped a, what teenager? Is that even allowed?
As for how do you get over him he talked about you not in a good light, he's not a boyfriend, just a "kid" who has no idea what constitutes a relationship say that to him, walk away and you'll feel better.
