I read extensively on this; nothing I have ever read has lead me to dislike Camilla.
The upper classes work in mysterious ways, have completely different values. Everything I've ever read, shows Andrew Parker Bowles was a complete womaniser, and it suited both him and Camilla, APB had affair after affair. But, it's not something that seems to bother the upper classes, they were a happy couple, he had his multiple interests, and she had her relationship.
Diana, product of a broken home, needy, attention seeking, personality disorder, how did she ever pass the bride test? Even her own Grandmother knew she was dysfunctional.
When Diana did that interview, ostensibly to justify her own adultery and vilify Charles, all she did was force APBs hand, he and Camilla had to agree to divorce so he (APB) could save face. Diana was no idiot, she knew she was savaging the Parker Bowles children's home life as well as her own childrens by going public. Those boys,having to watch that (pardon the pun) car crash of an interview in their headmasters office, where she's discussing her shags. That isn't a decent mother, it's an attention wh*re, much like some dope hanging her dirty washing out on todays social media. She just had a bigger platform to play the 'woe me'
Everyone else would have gone along quite happily with the status quo. Camilla and Charles would have stayed FWB, APB would have worked his way through his friends wives, Diana would have continued picking up and discarding playboys who saw her as a trophy.
I never quite get the Diana is a Saint malarky... Barry Manakee, James Hewitt, James Gilby, Will Carling, Hasnet Khan, Dodi Fayed ... and Oliver Hoare had a lucky escape but she tried her hardest to wreck that marriage too .....David Waterhouse was first her list of targets .
No spare me Diana, she might have looked good on the stamps, but she didn't have one bit of personal dignity about her.
