Emmy I get the feeling you are teetering on the fence about all this. That scares me. I would have had that order put in place IMMEDIATLEY.
As all have said he is losing it. You have to stop trying to be nice and amicable and for lack of a better word wishy-washy.
You have children to protect and obviously yourself. There are resources and people to help you out. You need to utilize them and get him away from you.
I would have changed my number by now.

Stay strong.
