Son (15) was accused of hurting a girl at school.

Hi all.I'm a single mother to a boy who is very sensitive and sadly has been bullied since early childhood. Both boys and girls have picked on him in the past, and after being beaten up by a boy last year, he took up weight lifting and muay thai to defend himself. I don't disapprove as I can see his confidence starting to grow, and he actually managed to to stand up to bullies previously thanks to this.However, getting stronger won't help much if you're being bullied by girls, and a group of them (apparently they're the pretty, smart girls who all the kids and the teachers love according to him) still pick on him every day, to the extent that last week he burst into tears as soon as he got home.They picked on him again yesterday, trying to film him eating, opening his rucksack and taking stuff out, etc. There is a girl, Rebecca, who isn't close to Aidan (my boy), but gets along with him. She didn't approve of what the girls were doing and shouted at them, and they laughed at her.One of the b*tchy girls, Eleanor, has a severe nut allergy, and when she kept mocking Rebecca she tried to shove her peanut butter sandwiches into her face. She was obviously terrified and teachers jumped in. She was OK, but she then started accusing my son of planning the move.This morning my son, me, Rebecca and her parents, and Eleanor and hers, were in the school office, where her mother screeched at Aidan that he was planning to kill her daughter. Rebecca made clear that it was nothing to do with Aidan and it was just a spur of the moment reaction, and she apologised. Eleanor insisted that it was planned and spun a whole sob story about how frightened she was.Rebecca was suspended, and the teacher said it will ''investigate further'' into whether Aidan had anything to do with it.I went to work, and today at lunch Aidan called me saying that he'd been called a ''girl basher'' and things like that.Honestly, I'm thinking of changing schools for Aidan, but I'm not sure if it's worth it as he'll be finishing Year 11 by May anyway.Advice? via /r/Parenting https://ift.tt/2OP7mVr
