Thanks for the replies!
I was all over google when I wrote this, and found out about the Motion for Temporary Exclusive Use of the Family Home.
So, I started with a letter to his attorney, telling him that I'm prepared to file the motion, and simply asked him to encourage H that separation (with a week's warning to the children) is needed. There were other things, too, so we'll see.
I have been sleeping in a different bedroom for months, so that continues.

I have now password protected my laptop and cell phone... I don't lock the bedroom, though, but it's a good point. Might get to that.
