My family is breaking apart because my nephew, age 20

From new member “aunt”:

My family is breaking apart because my nephew, age 20, is consciously trying to destroy his mother’s upcoming (we hope) marriage. Where do we look for a group home for him? We could pay rent/utils/food for him, but need a home with other men . Unfortunately, he’s not fully diagnosed because some well meaning official told him that he didn’t have to see doctors/take pills/let a doctor talk to his mother because he was over 18. We think he takes pot when he can, but no heavy drugs. His one bout with police scared him. But he has to live somewhere.
