I know that my stepson lost all his visitation rights over just this type of behavior. He hasn't seen his daughter in years. What about visits with supervision. If you don't want the court involved I would try a visit in your home on a trial basis. They could play a board game or something in the next room while you read or do a chore.With the understanding he needs to arrive sober when he comes. Just a thought might be worth a try! Kerry
