Do not accommodate your son. If he returns to you he will never leave. He will not be seen as a priority and you will be seen as his carer so there will be no help from Social Services or NHS. You will not have a life and you may well die earlier due to the stress and strain of looking after him and negotiating care for him.
He needs to get into the appropriate sheltered housing. and most of all he needs to be with his own peer group.
So sorry you are facing these problems. do hope you can stay strong and negotiate now. All the best.
