I've been largely happily married for over 32 years, so yes, there are men who stay, who figure out how to work things through, and who show up even when it asks a bit more of them than they had originally expected (we have an autistic son). So, it can and does happen, but sadly, it doesn't seem to be the most common dynamic.

I'm glad you are regaining strength and balance. Wishing you all the best.
