Marriage to an alcoholic is no fun whether they are happy or mean drunks. Alcoholism sucks. It does not make for a good family relationship!
Glad you're here. She will just continue to do what she will do - which in the case of a mean drunk is just more mean drinking.
But you, you are free to choose joy in your life. It may take some doing, but you can find peace of mind whether she drinks or not!
Peace-
