I just wanted to say that I am here for you. I am the 21 year old daughter of 2 alcoholics, and a drug addict myself. My father put himself into the hospital in november after I begged him to go get help after not speaking to him for nearly 2 years while living in the same house. He was told that he had a fatty liver and had to stop drinking... unfortunately, he only stayed sober for a month.
I know that your situation is a very scary one... Stay strong MG! Above all, take care of yourself and your children, because no matter what he decides to do, you need to be there for them and they'll be there for you even if they don't understand whats going on.
