She decided to yell at me after therapy. Didn't engage just listened for a little bit the walked away. Last night I let her sleep in the bed while I slept in the living room.
Did your therapist say it would help your ulcers? Maybe it's just me, but standing there listening to your W yell at you, is not effective action......or healthy. Why not try holding up your hand in the stop signal, and saying, "I won't stand here and be yelled to, however, I will listen if we can talk civilly". That is you stating a boundary, and if she won't honor it, then walk away.
If she won't stop yelling long enough to hear you make your statement, walk away and tell her the next day when she has calmed down.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
