EXCLUSIVE: King Charles Made 'Improper Request' of Princess Diana Ahead of Wedding — With Pair 'Only Meeting 13 Times' Before Getting Hitched

One royal source told us: "Viewed through a modern lens, the episode is quite extraordinary because it underlines just how fast the relationship was progressing behind palace walls. By the time Charles was asking Diana for her views on Highgrove and encouraging her to become involved in decisions about the house, they had spent relatively little time together.

"Most couples would still have been getting to know one another, yet there was already an assumption that she would play a role in shaping what was effectively being presented as their future home. For Diana, the request carried a huge weight because she immediately understood what it symbolized"

"This wasn't simply a conversation about curtains, furniture, or color schemes," the insider continued. "It was an invitation to imagine herself living there as the future Princess of Wales, at a point when no formal commitment had yet been made. That naturally left her feeling slightly uncomfortable because she was conscious that their relationship had not reached the stage where such discussions would ordinarily take place.

"Those close to Diana later suggested she found the situation both flattering and unsettling. On one hand, it demonstrated that Charles was clearly thinking seriously about the future and saw her as part of it. On the other hand, it reinforced how quickly events were moving and how many expectations were already beginning to gather around her.

"It also offered Diana an early glimpse into the unique pressures of royal life. Decisions that might seem personal or domestic often carried far greater significance within the institution. She was suddenly being drawn into a world where assumptions about duty, marriage, and the future could move much faster than the emotional reality of a relationship."

"Looking back, the Highgrove episode can be viewed as a revealing snapshot of the dynamic that existed between Charles and Diana from the outset. Charles was already planning and thinking in terms of his future role and household, while Diana was still trying to navigate an intense courtship that had developed at remarkable speed," the source noted.

"In many ways, it foreshadowed the challenges that would later emerge as they attempted to reconcile personal expectations with the demands of royal life."

The relationship between the pair developed quickly after Charles first met Diana in 1977 while visiting Althorp House, the Spencer family estate, during a period when he was seeing her older sister, Lady Sarah Spencer.

Several years later, Charles began courting Diana, and their romance soon became one of the most closely watched relationships in the world.

Another royal insider said, "The pace at which Charles and Diana's relationship developed has long been one of the most discussed aspects of their story. When people look back now, they are often struck by how little time the couple had actually spent together before making a commitment that would place them at the center of global attention. The demands attached to becoming Prince and Princess of Wales were immense, yet their courtship unfolded in a remarkably compressed period.

"That is why episodes such as the Highgrove visit continue to fascinate historians and royal observers. They provide a window into how Charles was already thinking several steps ahead. He appeared to be envisioning Diana not simply as a girlfriend, but as someone who would soon be integrated into every aspect of his future life, from his home and family to his public role within the monarchy.
