I retired at 62 due to some health issues. Husband did indeed work until very near the end because he was a workaholic and loved his job,
When he was home, he was in the workshop, building his race car. I was always in the barn with my horses. We would have never survived a retirement that kept us attached at the hip 24/7 - he was and I still am far too independent. Husband passed nearly two years ago, but I am hanging onto this small farm and the horses.
My advice is to find something you have a true passion for and engage in it during the hours your husband wants to be at work, then come together afterward.
If you force the “I must be with you at all times” issue and he grudgingly retires, your marriage may very well go south.
