I have only read one biography of Wallis Simpson and that not completely, but I don't know how you could know whether she "loved" David but wasn't "in love" with him?
Indeed this is about Charles and Camilla, I was responding to the post above where they were comparing Charles and Camilla's relationship to that of the Duke and Duchess of Windsor.
I am currently at work, so this is what I've come up with just on the top of my head.
From Greg King's Book: The Duchess of Windsor.
"More than anything else, she appears a woman who.
in her own way, loved David greatly."
Emphasis Mine.
Didn't say she was in love with David, just loved him in her own way.
From Dancing With The Devil by Christopher Wilson:
"In the eyes of these adhearents, Jimmy put Wallis in a position to fatally compromise the man who had given up his throne, his crown and his empire for the woman he loved. For four years and three months,
the Duke of Windsor was cuckolded by, and remained in danger of being rejected for, a homosexual."
Again, Emphasis Mine.
Everybody knows about the affair Wallis had with Jimmy Donohue. In my opinion, if you are IN LOVE, really IN LOVE with somebody, you don't go screwing around on them.
From Owen Platt: The Royal Governor
"Always strong-willed,
Wallis now dominated Edward completely; on one occasion, in front of guests, she thumped the table and forebade him to give instructions to the servants "in my home."
Ditto the above.
Point being, marriage is a two-way street. It's built upon people who work together, no one has the upper hand in the relationship. I don't see that with Camilla and Charles. I noticed that to some degree with Wallis and David.
I see Charles and Camilla's relationship to be very healthy, give and take. I saw Wallis and David's as rather sad. She
did love him, he
did take care of her, but it wasn't the "Romance of the Century" that many have proclaimed it. David simply didn't want to be King and in giving up the throne, how could Wallis dump him?
Charles and Camilla have a very lovely, working, healthy relationship. They always have had this and they always will.
