Hi Gracey:
I agree with everyone else. Please report his threats to the police. They will forcibly remove from your home tonight. I believe they can only hold him for one night. So, tomorrow when he threatens you again, call the police, and have him removed again. Then on Monday, take few hours off of work and go down to the courthouse and file a restraining order. You need to keep yourself and your children safe. He is threatening you because he's panicking because he realizes that he's lost control over you. Who knows if he'll follow through with these threats or not, but you don't want to be around to find out.
Take the steps necessary to protect yourself and your children. Stay strong. Stay focused on your goal of a life free of alcoholism. Stay determined to find peace.
