Can you pull your child out midyear if the friendship fizzles?
Although advocacy is grueling can a reasonable education be had at the school?
I would be tempted to stay in school for the sake of the real friendship as long as nothing else terrible was happening. These friendships can last a lifetime so its worth a bit of a wait. It is possible that the parents are unwelcoming because they are also EG and have basically given up the hope of finding social contacts. In time they may hear enough stories about your son that things change.
good luck
