skella, when my son was out of control in this way, I got a no trespassing order---easy to get---not the same thing as a restraining order, though. I had to use it o ne time. I called the police, they were there within 3 minutes. They asked him to leave or be arrested--he left, quietly.
Yes, I have had to deal with relatives who had absolutely NO understanding of what I was dealing with. I learned not to expect support from them. I stopped talking to them about it in any detail. If they questioned me--I simply said, he is an alcoholic who is in denial and I am doing all I can to deal with the situation. THEN, I changed the subject!!! Now, I only talk to those who understand what it is to have a loved one who is an alcoholic.
sincerely, dandylion
