(((((So Ashamed)))))) Sounds like he is doing the mean, angry, dance. Not surprising, perhaps, but still not nice.
But, knowing that's what he is going to do, you are going to have to get a lawyer, I think. I know, you can't afford that either. But you will have to protect yourself.
Since it's a no-fault state, he can't use any of that "stuff" to justify things like this. It might even be possible to compel him to continue your insurance until things are finalized.
