My husband was just like this guy, but by the time he died at age 41, he had so many investments and a huge house without a mortgage, that I am still living comfortably all these years later. I never noticed he was cheap. We lived in the best part of town, drove Lincolns (used) and were aiming to join the local country club when he died. And our children went to private school, and any college they chose.
Sorry to hear about your husband’s death at such an early age.
I’m sorry to hear about your husband’s early death, but thankful he provided for you all.
