As time passed, Princess Diana started resenting everything about her husband, even his hobbies.
For Princess Diana and Prince Charles, the fairytale began and ended the day they said, "I do." The royal which was pumped with grandeur to make it the wedding of the century, but soon after they stepped out of St. Paul’s Cathedral as husband and wife, their marriage problems began and led to Princess Diana developing great resentment towards her husband.
As Princess Diana's hostility towards Prince Charles grew, she began hating everything about him, including his hobbies like painting, gardening, and playing polo, according to reporter and biographer Sally Bedell Smith.
Diana's resentment towards Charles even made her believe that her husband would never take the throne to be king. "Diana taunted him by saying, ‘You’ll never be King,’ and banished many of his old friends... Resenting anything associated with Charles’s previous life, she also insisted on getting rid of Harvey, his yellow Labrador, who was sent to live with one of the prince’s advisers," Bedell Smith said, as quoted by History.
Sources also say that Princess Diana believed their elder son, Prince William was more suited to be king instead of Prince Charles.
Paul Burrell, who was Princess Diana’s former confidant, told Yahoo UK’s The Royal Box, "His own wife said 'my husband is not fit for the top job.’ Diana said that."
Former newspaper editor, Sir Max Hastings also recalled a conversation with the princess about her husband in Diana: The Truth Behind the Interview, as reported by People.
"She said that all she cared about was William's succession to the throne," said Hastings. "She said to me quite explicitly — 'I don't think Charles can do it.' The outcome she wanted to see was for Charles to stand aside as heir to the throne and for William to occupy the throne. This was pretty dynamic stuff."
Hastings claims that he could see how much Princess Diana "hated" her own husband as she told him there was never any happiness in their marriage.
"It became clear, first of all. How much she hated Charles," Hastings said. "Yes, she did hate Charles. And when I said 'were there ever happy times?' she said 'no, the marriage was hell from day one.'"
Although Prince Charles and Princess Diana didn't part ways for about a decade, they reportedly took to sleeping in two separate bedrooms. "That entailed Charles moving into a dressing room to sleep on a single bed, along with a well-worn teddy bear," Bedell Smith wrote, as quoted by History.
While Princess Diana was alive, she not only believed that Prince Charles should not be king but also thought she would never be allowed to be queen as well.
When she was asked in the BBC1 Panorama interview, "Do you think you will ever be Queen?" she replied, "No, I don't, no... I'd like to be a queen of people's hearts, in people's hearts, but I don't see myself being Queen of this country. I don't think many people will want me to be Queen. Actually, when I say many people I mean the establishment that I married into, because they have decided that I'm a non-starter."
She was also asked why the royal family might not be accepting of her being queen, to which she responded saying, "Because I do things differently, because I don't go by a rule book, because I lead from the heart, not the head, and albeit that's got me into trouble in my work, I understand that. But someone's got to go out there and love people and show it."
