Welcome from me too,
I too live with a functioning drinker and I have chosen to stay. There are no children at home, we don't fight and he is good to me. I deal with the drinking with the help of alot of program years and these wonderful people. And I too have happiness and serenity today. That is the great think about this life...we all have our own choices and none of them are wrong!
Hugs,
JT
