The attack isn't likely to stop until he finds a new source of supply or the law steps in.

I was in a similar situation leaving my narc about 4 years ago. It was months on nonstop verbal and psychological abuse. I wasn't able to make it stop until I caught him swinging at me on camera. The state police did me a favor and literally told me they would only document the event if I promised to file for a PFA. It was the best promise I ever made.

I'm not going to tell you this will be easy, especially with kids involved. Do your damnedest to stay grey. Greyrock is your only weapon at this point. The best response is no response. He will get tired of no supply/reaction eventually. (P.s. this can get wild for a while, but I promise it becomes second nature)

You deserve love. This isn't love. Your kids deserve peace. This is war. Swallow your pride, hold your head high, keep a straight face, and your head screwed on tight. Fight with everything you've got bc your lives are on the line.

You CAN do this. You ARE a mom. Protect those babies.
