I don't have any words of wisdom to share, I just wanted to say that I am sorry you and your son are having to deal with this. My DS, who is 7, is having to deal with the same thing right now. The only difference is that it is a girl who is bullying him and she is telling everyone at recess that my son is a "loser" and now his "friends" don't want to play with him. She went so far as to push him to the ground today too.
It is so painful to watch our children suffer and have to try to help them make sense of the fact that people can be mean. I guess I just wanted to say that I feel for you and to let you know that you are not alone.
Good luck with whatever you decide.
