The couple, once thought to be inseparable, have faced speculation about infidelity and relationship problems, leading to rumors of a split. Catherine is a commoner who fell in love with a prince. The royal couple have been married for more than a decade, but people often reflect on their beautiful wedding day. Over the years, they have faced various challenges, including health issues, family scandals, and conspiracy theories. They have also dealt with a strained relationship with Prince Harry and Meghan Markle.

The past five years have been really difficult for them, especially the last year. Such challenges can strengthen or weaken a marriage. Their unity seems crucial to the stability of the monarchy at this time. A year after Catherine was diagnosed, she feels renewed and she seems more popular than ever with the public. Catherine's parents, Carol and Michael Middleton, have provided much emotional and practical support to the royal family. Although they have rarely spoken in public since Catherine married William in April 2011, they have a close bond. This bond was evident on her wedding day when Michael walked her down the aisle. Minutes earlier, William had lightened the mood by sharing a joke with his future father-in-law about the size of their wedding, which was attended by nearly 2,000 guests and watched by millions.

William expressed his affection for Catherine during the carriage ride after their wedding, telling her that she looked very happy. She responded in the affirmative and asked if he felt the same way. He confirmed that he did. During the ride, he also shared some tips on royal etiquette while commenting on the lively atmosphere around them. He was earlier seen admiring Catherine's stunning wedding outfit, which included a $250,000 Alexander McQueen gown and Cartier tiara.

With Catherine's return to public life following her remission announcement in January 2025, she and Prince William have once again been in the spotlight, both as a couple and with their three children. Known for his passion for sports, especially rugby, William supports the Welsh rugby team as the Prince of Wales, while Catherine supports England. Their shared passion for sport continues to raise their public profile and strengthen their relationship, highlighted at the recent rugby match between England and Wales at Cardiff's Principality Stadium.
