Hello and welcome! I think you are doing all the right things. You will hear quite frequently on here and from Alanon, You did not Cause it, You cannot Control it, You cannot Cure it. You are right to get away. I am in the process of divorcing my alcoholic husband. It is a life of misery for those around them and it progresses unless they realize for themselves they need help.
Good luck and God Bless!
