I do see your point... and of course I want her safe-
I called often while she was there to listen to see if he was slurring or she was in distress. She was fine (and funny) and he just sounded annoyed. I'm thinking that getting her equals staying sober then he will just find a reason to end the visit. She is allowed to come home- just not go back and forth. I do make plans (to work, do chores outside the home, etc) and I really wasn't allowed to get anything done because I had to constantly replan my weekend. Now if she comes home I just replan once to include her and move the other stuff to when I have childcare during the week (or hire a sitter).
The conversations are a fine line... enough to keep him revealing, but not enough feel like he is invading my personal space. It is pretty tricky.
As far as the court goes... there is a two year waiting period to be heard for any non-emergent changes. Besides, visitation is a guideline that says when he is allowed- he can pick zero visitation and that he isn't in violation of any orders.
