In 2006, before their marriage, the Prince and Princess of Wales found themselves embroiled in a serious argument.
Reports from Mirror suggest that Kate Middleton once experienced a moment of deep concern, fearing the potential loss of Prince William.
Before tying the knot, the couple faced periods of separation dictated by Royal tradition, which mandated their absence from each other during certain holidays.
During one such occasion, William's sudden cancellation of their plans left Kate in tears, grappling with the uncertainty of their relationship.
Their lives, along with the destiny of the monarchy, could have taken a different course if Kate's fears had materialized.
According to royal author Katie Nicholl's 2011 book, "The Making of a Royal Romance," William had initially promised to spend Christmas with Kate in 2006. However, he ultimately chose to stay with his own family, breaking the news to Kate over the phone.
The author recounted, "William had been wrestling with doubts and sought counsel from his father and grandmother regarding his future with Kate. Both advised him against rushing into anything."
In 2007, the couple briefly parted ways, with sources later revealing the disappointment felt by the late Queen regarding the breakup. However, their split was short-lived, as William and Kate were spotted sharing a kiss at an army party in Dorset shortly after.
In July 2007, Kate and her brother James attended the Concert for Diana at Wembley Stadium, commemorating 10 years since the passing of William's mother, Princess Diana.
Their romance quickly reignited, with Kate eventually moving into William's Clarence House flat. They would spend weekends together, cozying up after his return from military duties, marking the beginning of their enduring journey.
In 2010, the couple announced their engagement, followed by a grand wedding ceremony in April 2011. Nearly 13 years later, they remain happily married with three children: Prince George, Princess Charlotte, and Prince Louis.
