Without a doubt, Princess Diana was the one who gave and loved more during her short-lived relationship with Prince Charles. However, it did not stop her from speaking up about his husband's ill-fated affair with Camilla Parker Bowles.
In November 1977, the then-16-year-old Princess Diana met the heir to the throne, who happened to be dating her older sister. Prince Charles saw Princess Diana as her potential bride and their relationship progressed. Athough they had almost a 13-years age gap, it did not hinder them and Charles proposed to her on Feb. 1981.
Seeing how over 750 million spectators waited for the Wedding of the Century on July 29, 1981, the Princess of Wales thought that everything between them would work out in the end since it was Prince Charles who chased her.
Unfortunately, it did not.
Through their married life, their relationship became damaging. It turned to be even more problematic when Prince Charles restarted his romantic entanglement with Camilla.
Princess Diana, who was eager to save their relationship, spoke to her husband countless times and stood up bravely and confronted Camilla for the first time at her sister's birthday party to let her know that she was aware of her husband's infidelity.
Nonetheless, it was not enough to convince the two that Princess Diana ended up talking about the matter in public.
In her tell-all biography written by Andrew Morton in the book entitled "Diana: Her True Story", she revealed that they were unhappy since there were "three people" involved in the marriage.
Prince Charles' infidelity was also mentioned in "Diana: Her True Story - In Her Own Words," saying that what the royal prince did make her miserable, and she wanted to speak it all out so the world would know her side and what she was going through.
In 1995, Diana appeared in the BBC's Panorama Interview with Martin Bashir where she finally convinced herself that she could not do anything about his husband's affair anymore.
"But I wasn't in a position to do anything about it," Diana said. When asked how she knew, she said, "Oh, a woman's instinct is a very good one."
Prince William Thought What She Did Was "Too Much"
In the ITV documentary "Prince William at 30," it was revealed that Prince William thought that her mother has "gone too far" when she brought humiliation onto the Royal Family in the aforementioned Panorama interview.
Katie Nicholl, a royal commentator, also said that the Duke of Cambridge snubbed Princess Diana for days, and the mother felt the worst considering how close they were.
"He was desperately upset, could not believe that she would lay her soul so bare," BBC's ex-royal correspondent Jennie Bond said.
Despite the dismay he felt towards her mother, the Duke of Cambrdige still did everything to cheer her up and protect her. The then-14-year-old Prince William left words of love for her mother and helped her survive the tormenting event.
The narrator of "Prince William: Royalty in My Family" claimed that the duke wanted to end Princess Diana's suffering as soon as possible. However, a speedy divorce meant Princess Diana would need to give up her royal title.
"You'll still be mummy," Prince William said, trying to comfort his mother.
The Duke of Cambridge protected the royal princess until her relationship with Prince Charles officially ended in 1992 and formally divorced in 1996. Diana, however, tragically passed away when she got into a car accident in Paris a year after the split.
