Kristen- First of all welcome.
If begging and pleading your loved one to stop drinking actually worked; there wouldn't be any alcoholics.
If being threatened, coerced, or guilted into stopping actually worked, every alcoholic would be able to put the bottle down.
Unfortunately, none of those work. You can't love an alcoholic into sobriety. All you can do is take care of yourself and your children.
Only 3 things stop alcoholics from drinking; their own desire to stop, jail, or death. You have no power over him. Only power over how you react to his drinking.
