Just my opinion, but I think he is trying to use fear to control you.
Deep breath... if he thinks you can't pay the light bills without him, how does he think that you are going to be paying him, alimony?
I think he is trying to push you buttons. A form of sabatoge.
Also, trying to start a fight. Good way to stay engaged?
Stay focused! Don't let him defocus you.
Before listening to all of his quacking, contact an attorney. His attorney can call yours with all his threats. They have thicker skin!
