Its a tough story and it feels like champagne problems with regards to the money at the same time.
No offense but 37 with a minimum of 11m you got plenty of options and probably no need to ever work again.
Ask your self what you want for yourself in the absence of trying to fix a broken mariage or a broken spouse.
What can you reasonably control, what realistic ways forward ?
Take 3 steps back and make sure you see the bigger picture and are clear headed. If you are stuck in day to day drama and obligations you wont look at this objectively. That requires distance and perspective. Be sure to get that somehow.
Good Luck. And remember if it costs you your freedom/sanity its too expensive.
