I'm not sure I agree with classifying Camilla as a victim. In my opinion, it's a bad idea to pursue someone you know is married particularly if there are small children involved. I don't care if your interest is a future king or a future sanitation worker.
Besides, if I am not mistaken, CPB was not the only woman involved with Charles during the time he was married to Diana. So, I am not so sure this is a great example of a happy-at-last story. Even future kings are allowed to step aside and marry for love.
For hundreds of years, women have been competing for the attention of men. It used to be done for survival. That we still do it when we no longer need to is just so sad.
