Prince Charles might have seen divorce as the best option to make everything less painful for Princess Diana. However, it was never painless.

The Princess of Wales herself came from a family whose parents ended up getting separated, and the pain she felt when her parents got divorced repeated once again.

Throughout her married life with Prince Charles since their grand wedding on July 29, 1981, Princess Diana tried to win the heir to the throne's heart that she forgot to protect her own. 

Aside from the fact that she knew Prince Charles restarted his romantic relationship with Camilla, it also broke her heart when the Prince of Wales threw her away in an interview.

The two appeared in a television interview after their engagement where they were asked if they were in love. Princess Diana, of course, responded that they were even though she already knew that their marriage was one-sided.

Prince Charles, on the other hand, said he "supposed" to, before starting the three-word line which hurt his wife: "Whatever love means."

Princess Diana talked about how she felt through a video from 1992 and 1993. Channel 4 released the said clips in a documentary entitled "Diana: In Her Own Words," where she said that Prince Charles' answer "threw her completely and it traumatized her."

Diana Knew It Was Not Her Since The Beginning

In Andrew Morton's book entitled "Diana: Her True Story", Morton stated that on the busy streets of London, as she walked down the aisle at St. Paul's Cathedral, Princess Diana already saw the sign.

Princess Diana reportedly spotted Camilla, who became the cause of her failed marriage with Prince Charles.

"So walking down the aisle I spotted Camilla, pale grey, veiled pillbox hat, saw it all, her son Tom, standing on a chair. To this day you know - vivid memory," Diana said, as what the taped conversations for the novel recorded.

Diana held onto the failed marriage until they got divorced in 1996.

Diana Hoped For a Different Outcome

Princess Diana saw the warning but still did everything in hopes that Prince Charles might still change his mind. But her dream to have a complete family lasted only for a day, and it stopped there as she never had the chance to win the heart of Charles from Camilla.

She still tried, however. Diana even opened up to Martin Bashir during her BBC's Panorama Interview about how much she wanted it to work out.

"I think like any marriage, especially when you've had divorced parents like myself, you'd want to try even harder to make it work and you don't want to fall back into a pattern that you've seen happen in your own family," Princess Diana said.

The Princess of Wales thought that they could make it since she loved him so much and thought they made a good team together.

Nonetheless, nothing ever happened according to what she wanted, not even once. Prince Charles set his future with someone else long before they got married -- and he only wanted Camilla.
