Charles has never been a happy man until he did marry Camilla. We know this and it is obvious in his photos with her that he adores her. But Charles doesn’t exactly have his marbles all in a row either....some of the things he says are way off the cuff.
I don’t believe I can tout their relationship as a “romance” all those years, better an “adulteress relationship” for that is what it was....they both tore out the hearts of the people they did marry in order to keep their relationship on the front burner.
An "adulteress" is a female person engaged in an affair while married/a female, engaged in an affair with a married man; you used the wrong word.
Charles never loved Diana and it showed from the very beginning, when they were just "dating".
Sometimes arranged marriages work, lots of times, when it's royalty, it doesn't and in spades.
So if Charles had loved Camilla more than himself and the role of King, then he would have married Camilla and spared Diana, Camilla's ex husband, William, Harry and many others all the evil he delivered to them.
