My stomach is in knots from just reading your post.
This sounds like a very good plan to me:
I think I will talk to his family about supervising so that they get a chance to see their grandkids more. Also I don't want to supervise because I am at a point in my own recovery that I need to stay away from the hooks of AH that keep me engaged...in order to detach I need space. I am also going to start documenting incidents and am going to photograph the condition of the house in case some kind of investigation or custody battle is in my future.
