How do i deal with mum’s drinking without losing the kids?

Q. You recently wrote about a mother dealing with her ex’s drinking and I wondered how many men are in a similar position. I know I am. Mum drinks at home four or five nights a week, either on her own or with friends. The kids, who are teenagers, are watching this all the time. I protest about it and am told to mind my own business and threatened with separation and/or being thrown out of the house. The kids are now losing patience with it and get very cheeky with their mother when she has had a few drinks.
