I think I'm going to have to break NC and try to calm him down. He's out of control.
This is probably exactly what he wants. If he can't have a good relationship with you, he wants to maintain a conflict with you. Anything to keep you in his life. That's what my ex did, that's why I'm still paying lawyer fees -- because he kept dragging me back to court or doing things that put us back in court.
Leave it. See if you can get the state troopers to escort you to get whatever he may still have that belongs to you AND get a restraining order.
