Run. Move. Get away for your sake & your family.
Get a restraining order.
He sounds like one sick b*stard.
You don't need him stressing out your life anymore.
To me it truly sounds like he's stalking & bullying you.
Don't give him any part of you anymore.
Don't talk, respond, or reply to him.
The best thing is to "completely" ignore him.
Otherwise, you are still playing his game with him.
