perfect just what i need! part 2

Great now he is in my pe class and we are doing a dance unit. So i might have to dance with him and i dont even want to talk to him. What do i do? I cant handel him in any more of my classes. I dont want him in my class because he was so mean to me one day. He started calling me emo and a nerd and started to cuss me out and say he never wanted to talk to me again. But the strange thing is in my math class he was waving and i did not want to wave back. He is always where i am in class. Ex- i sit in one corner teacher says to sit with friends him and his friends sit next to me!!!
