Gracey -
You asked if there is anything you can do to get him out of the house and the answer is yes. You have contacted the police before - there is a record of that. Call them and tell them what is going on. Ask them for advice. Call a Crisis Hotline. Call the Victims Assistance Program. They can all give you advice. He is threatening you and your kids. File a police report. Ask the cops to remove him because you are afraid for your life. Tell them what he has said. Tell them that he has physically abused you as well in the past. They should help you. He can go and live with his mother and that should make the two of them very happy! Make a call Gracey, and protect yourself.
Hugs, Jo
