Forgive me, but can I interject here? It seems that your W is about to explode...anytime soon. She has a great deal of anger "towards herself" that she is clearly projecting on you. It is clinically called projection. You are receiving all the anger from her, but she is angry only at herself. By not reacting to her outbursts or walking away, it will make her more angry...but she needs to hit rock bottom before she'll stop.
