Hello codeflayer
Welcome to SR!
You pretty much have two choices. Do what you need to do for the kids and yourself that removes the insanity of alcoholism from your lives, or wait for her to address her problem and start a program of recovery.
You can't force her, and you can't do it for her. Alcoholism is progressive, this will only get worse and worse.
Please, do take some time to read down in the Adult Children of forum to see just how damaging it is to children living in a home with an active alcoholic.
