Catlady,
This may be the pefect time to leave things alone. What they do with their children is their business.
When my son was having his way I warned him that I would not visit him in jail. He of course just shrugged it off. Then his DUI got him sent to jail for 90 days, and I did not visit once. He didn't need visitors to keep him warm or fed, the county did that. He was there because he had no regard for consequences.
