Okay, I have a question in all of this. What is this doing to your children? You are worried about them becoming more attached to him. Maybe take the focus off from him, put it back where it belongs, on your children and their mommy because you can't be an effective parent if you are all stressed out over him. I hope you get your focus back. And maybe it is time that he makes other living arrangements. My daughter is in a halfway house where other addicts can call her on her sh*t. Sending hugs and prayers, Marle
