There were instances during the honeymoon where Princess Diana was "raging and getting no meaningful reassurance from Charles."
It did not take long for Princess Diana and Prince Charles to realize that they were not right for each other. Before getting married, they met just over a dozen times and then tied the knot in front of the entire world. She landed the heavy title of Princess of Wales along with the misfortune of sharing an unhappy marriage with Prince Charles.
"We met 13 times and we got married," Princess Diana said in the documentary, Princess of Wales, as quoted by ABC News. "I was brought up in the sense that when you got engaged to someone you loved them."
She got married at the age of 20 to the most eligible bachelor in England who was 12 years older than her. The cracks in their turbulent relationship started forming right from the time they went on their honeymoon soon after they exchanged wedding vows at St Paul’s Cathedral. They could see how different they were while the royal couple's honeymoon kicked off with a cruise on the Royal Yacht Britannia. This ended up being a "disaster," according to royal author Penny Junor, who wrote about it the 2017 biography, The Duchess: The Untold Story, according to Express.
"It was a disaster, and only served to demonstrate how very little they had in common," the author wrote and went on to explain how Princess Diana and Prince Charles had two completely different visions for what their honeymoon would be like.
"The Prince envisaged a wonderful holiday in the sun, swimming, reading, painting, and writing thank-you letters," Junor wrote. "He had taken his watercolors and some canvases and a pile of books by Laurens van der Post, which he’d hoped they might share and discuss in the evenings."
On the other hand, Princess Diana was uninterested in spending her honeymoon with her nose buried in a book and she was even "offended" by Prince Charles' preferences. "Diana was no reader and was offended that he should prefer to bury his head in a book rather than sit and talk to her. She hated his wretched books. She resented him sitting for hours at his easel, too, and they had many blazing rows."
Eventually, Princess Diana could not take it anymore and she ended up acting out. Junor revealed in the book, "One day when he was sitting painting on the veranda deck, he went off to look at something for half an hour. He came back to find she had destroyed the whole lot... He had no idea what was wrong."
Prince Charles was "bewildered" to see his things destroyed while Princess Diana was left unhappy.
As part of their honeymoon, the royal couple also went to the Queen's well-known Scottish estate. According to Junor, when she spoke to the press at the time, Princess Diana said that she was having a "lovely" time at the Balmoral castle and said, "Balmoral is one of the best places in the world," as reported by Express. But "nothing could be further from the truth," Junor wrote.
"She hated the countryside, hated his family’s passion for horses and dogs, hated the rain that poured down remorselessly; and she felt that her husband was avoiding intimate contact," the author said. "They didn’t stay in the main house, but they had dinner with the rest of the Royal Family several times a week and, as usual, his friends were invited – though not the Parker Bowles' – so there was very little chance for the sort of intimacy she’d hoped for on honeymoon. She was raging and getting no meaningful reassurance from Charles."
It seemed as though Prince Charles was avoiding having to deal with Princess Diana's unhappiness by going out and doing what he usually does in the countryside. The task of "dealing with Diana" was left "to others."
During the honeymoon, there was one time when Prince Charles went out on the estate while his secretary, Michael Colborne, kept Princess Diana company. The secretary could see how distraught the princess was and even witnessed her kicking furniture.
"There followed the most shocking, distressing, and draining days of Michael’s life," Junor wrote. "For six solid hours, with no distraction beyond a plate of sandwiches at lunchtime, he sat there while Diana cried, paced around the room, kicked the furniture, ranted about everyone and everything to do with the place she hated so much, and then fell into brooding silence before starting all over again."
As for Prince Charles, he was "mystified and despondent. He didn’t know what had gone wrong or how he was going to cope."
Until about a decade into their marriage, Princess Diana and Prince Charles remained unhappily together before they decided to separate, according to Town & Country. After about 15 years since they tied the knot, the royal couple officially got a divorce in 1996.
