Many people think he may have mishandled his relationship with Charles, such as overencouraging the marriage with Diana for dynastic reasons while Charles’ heart was not in it.
while that’s true- Charles made the decision to marry someone he clearly did not love.
(overbearing parents are the worst, and I can’t imagine Royal overbearing parents. They bring it to new highs!)
Camilla had dumped Charles and was long married by the time Diana came along.
