Wow...SB, you do need to stop visitation. A judge will listen to the girls if it is what they desire, they are old enough. What a lousy night for our babies, I am so sorry.
It is probably best that H is away and they will not see him, it does not sound like this is healthy at all. I think I already mentioned how strongly I feel about him using your daughter as a way to communicate with you. It looks as if also a little transference is going on in terms of anger etc. it is probably best they don't see him for a bit
