Getting worse and harder

[Painter]

It sounds to me like she is expressing her fears. If I were you, I would acknowledge her feelings and tell her you're not drinking. I'd be very brief, just a sentence. "I understand that you are worried that I am drinking, but I assure you I am not." I would think that the calmer you stay, the more convincing you will seem.

You don't have to do anything besides making sure your kids are taken care of and get time with you. Focus on yourself and what you can do to improve yourself. Let go of the situation with W, you can't control this or fix it through direct action.
