William and Catherine book details cautious approach to early royal relationship

Prince William reportedly exercised significant caution during his lengthy courtship with Catherine Middleton, implementing a series of informal tests before their 2011 wedding.

In his new book, William and Catherine: The Monarchy's New Era: The Inside Story, Russell Myers reveals how the Prince of Wales sought to protect his future wife from the overwhelming nature of the British monarchy.

"The prince had invited his girlfriend to stay at Highgrove on several occasions, and they had also enjoyed a weekend together at The Queen's Sandringham estate," Myers notes.

These visits were meticulously arranged for times when the senior royals were away, providing the couple with essential privacy.

Myers explains: "The stays were organized by William for when his father and grandmother were not in residence, allowing the couple the freedom to enjoy themselves without Catherine worrying about meeting his family."

The Prince remained acutely aware of the vast cultural difference between Catherine’s upbringing and the demands of the Crown.

"He was very concerned she would be completely overawed by the whole thing," the courtier continued. "Kate had wealthy friends who had nice piles in the country, but it's a different story when you're dating a prince whose granny is The Queen." 

Furthermore, he prioritised a gradual pace to safeguard their bond. "He was still very much in the mode of 'Let's take it slow and see what happens,' while being pretty nervous that the press was going to find out what was going on and ruin it for them," she said.

The couple, who first met at university, now balance their high-profile duties with raising three children.
