I was speculating that things might have worked out differently if Diana toed the line. If she kept quiet and didn't make a fuss in public or private (not even unloading to her closest and dearest friends / relatives), did what was expected of her (carrying out her royal duties and not really making her mark so as not to become a media darling), life might've turned out differently. She and Charles would be together. Not happily for her as Charles and Camilla would be carrying on their affair. The boys might've turned out differently. They might've accepted whomever the "firm" selected for them and, like father, like son, have long term affairs.
Then it would have been a no win situation. If she looked dull and did not relate well with the public, it would have been bad for her and she would have been criticized. She was nervous and scared on her first walkabout in Wales but the public took to her and she was a natural with them. I think no royal spouse should have to suppress any "gifts" or abilities she would have. Then she'd be criticized as well. How could she be "prevented" from being a "media darling," stay home, then she'd be criticized too. Diana did very well in her royal work and that's the way it should have been. Charles perhaps should have spoken to someone to deal with his concerns about the public taking to her. It was later on when the two separated that there was "competition." NOt in the early stages. Charles as early as 1983 "joked" in front of Diana that he needed "two wives." He was the one who perhaps should have worked on his attitude.
I think Camilla wanted more than being a mistress. She was not "traditional" in the sense that she put down the wife (a letter came forward that she called Diana that ridiculous creature). Traditional mistress in days of yore, like Edwardian times, would not have dared to insult Alexandra. Edward VII would have put them in their places. Also, it is rather soul shattering for a woman to have to put up with a mistress around in the first place. Even Alexandra who "looked the other way" was said to practice passive aggression with Edward.
No woman even royal should have to put up with a mistress. Charles should have not kept one after his marriage. Even his involvement pre marriage with married women, Dale Tryon and Camilla Parker Bowles was not exactly the best choice he made.
Maybe Charles should have toed the line.
I think Charles and Diana got along after the divorce but they'd not exactly be buddy buddy. I think there was some wariness between them.
