Fd,
Welcome and good for you for reaching out. I second the motion of calling the police. He is not your responsibility anymore. Do you want to be doing this in 6 months or a year. Its not normal or healthy for anyone. He will not stop till you stop him. I hope that he would if the police arrested him for public intoxication.
I agree also with MIR, you could really educate yourself by hitting an alanon meeting. They are wonderful for face to face support. They are near you and you could reach out to them for support and suggestions on how to help you.
hugs my friend, I am sorry!!
