When Prince Charles and Princess Diana married in 1981, they appeared to have a fairytale wedding. However, their marriage was riddled with pain, heartbreak and scandal.

According to a royal expert, Diana’s need for attention during the early days of their union may have caused the Prince of Wales to become jealous of his wife.

In the book, “The Queen & Di: The Untold Story,” Ingrid Seward revealed Princess Diana attempted to stop Charles from attending an event. However, the dramatic gesture caused a scene at Sandringham that left onlookers “stunned” by her behavior.

“Diana wrenched at the car and then threw herself, first on to the bonnet of the car, then finally on to the gravel, crying and pleading: ‘If you love me you won’t leave me, you won’t go.’”

Forced to choose between his hysterical wife and a planned event, Prince Charles stuck to his schedule and left his wife on the ground. Although Charles was unhappy with his wife’s desperate attempt to get his attention, Seward claimed Diana couldn’t stop herself from acting out.

“Diana needed attention in much the same way a drowning man needs air, and she pushed aside the restraints of both common sense and court protocols in her frantic attempts to get it. She demanded it of her husband, sometimes to an embarrassing extent,” Seward explained.

While Prince Charles may have come off as cruel for ignoring his wife’s pleas, the biographer claims the royal may have been jealous of Princess Diana.

“Diana later described such scenes as a desperate cry for help. Charles saw them in a different light. He has soon come to the conclusion that his wife’s demands were illogical and impractical,” the author shared.

“There was an element of jealousy in his thinking: as heir to the throne he had been brought up to be the center of attention, and he did not like being upstaged - this was precisely what Diana had been doing almost from the first day of their marriage,” Seward added.

During her time in the royal family, Diana became known as the “People’s Princess” and was praised for contributions. When she and Prince Charles divorced in 1996, she remained in the spotlight and continued to be favored by the press and the public.
