To be clear, I AM advising that she go dark. Ideally, she would do that right after a more POSITIVE interaction with her husband, but I think the most important thing right now is to limit further damage by emotional outbursts.
mdu's husband is not presenting as a man who is "willing to do whatever it takes," or even necessarily as someone who is committed to reconciling. I would have preferred mdu to stop that interrogation (and I too felt like it was an interrogation) VERY early, and say something like "So here we are, and now with a new wrench. What can we do here, what are your thoughts, H?" -- and bounced it RIGHT back to him, where it belongs.
I think the power equilibrium is all outta whack here, and mdu's GOTTA find a way to get it back.
My opinion only. I have the utmost of respect for Wonka, and when your husband is ready there is no one I would rather have calling the day-to-day advice shots. I just don't think he's ready, mdu.
