+1. Best answer so far.
As we age, character traits that seemed mild or insignificant
can become dominant.
The young fashionista becomes plastic-surgery addled, appearance-obsessed in middle age.
The man who was "macho" (like OP's husband) when young becomes a crude, misogynistic 50 year-old.
It's not inevitable, but it certainly happens--usually to those (a) with self-esteem issues, or (b) who are fundamentally disappointed in the course of their lives. The character trait becomes a sort of defense/denial mechanism.
Unfortunately, it often only gets worse as people age further.
