My autistic

Son was attacked last night by a stranger on the bus when he was coming home from school. It's not the first time it's happened. I am seriously thinking about leaving and taking the kids to live in Cornwall. I've been thinking about it for a long time. In the line of work I do I can find work, and I can change the kids schools etc. I'm scared for my son and for his future in a city where it seems everyone is mad. If you could would you make the move?
