Way more than I bargained for

The demon is now threatening to show up at my home so of course I cannot sleep. He is trying to coerce me into being with him by promising me that he will go to treatment if I agree to marry him when he gets out. His new theory on why I can no longer see him is that I am screwing his best friend. The boy is beyond delusional. So I am sitting here fully dressed at 2:30 in the morning just in case he shows up. Not quite sure what I'll do. Call the police? Talk to him? Hide inside and hope he goes away. He is now threatening to kill himself and all his children. I called the police and also the children's mother. i never bargained for any of this.
