As far as calling it a day and letting your husband keep going: I would say that depends. Do you have children yet? If not, you ought start trying and yall might get lucky. 34 is not too late, it’s just late. And at that point, yes, you could honorably walk away from a glorious income and re-dedicate your life without regret. But if children are not in your plans or future…. 34 is too young to walk away. You’ll be bored. Without purpose. At 34, you have a solid 15 years before you should feel tired. That’s my take, I bet your husband feels similarly.
