iwc,
Is it posssible for you to leave the man alone?
He knows what treatments are available.
He knows you think his drinking is the cause of your relationship troubles.
He knows that you are worried about the combination of alcohol and depression.
He knows that you will continue to threaten to leave, but not follow through.
He already knows all this because you have already told him.
Why are you so intent on changing another person?
He does get to be who he wants to be. He loves drinking. It's his #1 priority.
That is his choice, dearest.
All YOU get to decide is what you want in your life.
You don't get to make him into it.
