That's where I had a hard time detaching. It's unacceptable for our partners to treat us that way. Saying nothing or simply leaving the room doesn't send a strong message that we demand and deserve respect, IMHO. That's why my solution was to remove the active alcoholic from my household.
We each have to find a solution that allows us to live a life filled with happiness, serenity, and dignity. Keep working on yourself and you'll find the best solution for you.
