WOW,
I think something you wrote in another discussion explains why your son is OTD and hangs out on the street: “He went through a tough period in school where the kids made fun of him…”
His school friends don’t accept him, whereas the street kids do.
It’s good that all adults are showing him love, but I think that he needs acceptance from his own peer group. It seems to me that he may need a new peer group. Even if his present (or should I say past) group of classmates don’t bother/ostracize/reject him, they still have lost all credibility with him. He will not forget what they did to him.
