@Supergolfer12 I hear you and I am not sure I have the ability to suggest ways to avoid maximum damage but here are options.
Get her into a residential treatment program. very difficult because in denial.
Find a friend of hers or relative that is willing to take her in.
Ask your therapist the how to do this. They know you and the situation best.
Get her into couple therapy to try to get to the problems she is masking with alcohol.
You could set boundaries and tell her those boundaries are conditions for her staying in the house. Work those out with your therapist if you think that is a tenable idea.
Sorry these are only options; only you can decide what will do the least damage and end your support of her.
All the best to you.
