If you were to leave your current job, how difficult would it be to rejoin the workforce if something were to happen that significantly reduced your husband's income? How does your husband feel about you quitting your job? Are there cutbacks you would have to make in your current lifestyle that would be required if you were to quit your job? How willing are you and your husband to make those changes?
It always amazes me when people think they would be bored if they retired/quit. There are so many things you could do even if you aren't working, especially in non-COVID times.
If it were me and my husband were supportive, I would quit in an instant, but, obviously, you have your own priorities.
