I was never one who was bothered about the idea of Charles and Camilla getting married when it was announced. I was surprised, definitely, but I never disliked or disapproved of the idea.
I realize that they both made mistakes and that committing adultery is immoral and was hurtful to the people around them such as their respective spouses and their children, and for Charles, for the monarchy as a whole. But they are also human and in each other (especially Charles), they found another person to lean on and to count on for support. Maybe they could've gone about being together a different way, but then their story wouldn't be as interesting as it is.
And since becoming a member of the royal family, daily I am impressed and charmed more and more by Camilla. I think she's taken on her royal engagements with a great amount of dedication and interest and people certainly respond to her well and warmly. And from the visit to the U.S. to this current trip to Saudi Arabia, I am more impressed by Camilla with how she handles herself with respect to the places she visits (mosques or memorials) and with the individuals she meets. I can't think of a single additional thing I'd ask for about in a princess. She conducts herself with an earthliness and humbleness that I think is wonderful. She doesn't put on airs and isn't so outrageously lavish in her attire.
Nobody in the royal family seems to be indifferent to Camilla and in fact respond and interact very warmly with her (as evident by the recent memorial service where she was greeted with a kiss from Sophie and chatted on the church steps with Princess Michael and Princess Alexandra), Harry and William, from what little they have said, have been positive about Camilla. And finally, Charles absolutely glows and is so much more animated and happy in her presence. Despite the hurt of the past, I'm glad to see him happy again; I think it's deserved. And in the long run, a happy Charles will make for a happy William and Harry and a happy monarchy.
