Who cares... in 1981 the biggest marriage in history was between Prince Charles at 31 and Lady Diana at 20.
They dated when she was a teenager... and everyone celebrated.
I personally don’t care.
I dated a 31 year old when I was 18/19 in Alabama in 1980/81.
We were not unusual in our circle. All of the musicians I knew at that time dated younger women.
Even the married ones.
(The legal drinking age was 19 at this time.)
