Prince Harry's severed bond with Prince William after marrying Kate Middleton

Prince Harry's once-close relationship with Prince William and his sister-in-law, Kate, Princess of Wales, reportedly underwent a significant shift after their marriage.

According to insights from Tina Brown, the former editor of The New Yorker, the Duke of Sussex began to feel "bored" by the future king and queen.

Despite their previous closeness, which involved living next door to each other at Kensington Palace and spending ample time together, Harry allegedly mourned the special "us-against-the-world" bond he once shared with William. 

Brown emphasized that the dynamic between the brothers changed, leaving Harry feeling somewhat displaced by the newly-formed family unit with Kate.

Harry's apparent struggle with his brother's intense connection to his in-laws also contributed to the shift in their relationship. 

The author of The Palace Papers further observed that Harry found Bucklebury, the Middletons' hometown, uninteresting and uninspiring, in contrast to his previous experiences.

As reported earlier, the elopement of Prince William and Catherine had a profound impact on Prince Harry's relationship with his brother, possibly leading to feelings of jealousy. 

The trio of young royals, often affectionately referred to as "the Three Musketeers" by the British press, seemed inseparable in their early years. 

Harry, along with William and Kate, enjoyed a close camaraderie, frequently going to nightclubs together during the 2000s. 

However, everything changed in 2011 when William and Kate's swift commitment to royal duties altered the dynamics.

Harry, the youngest of the three, reportedly began to feel "displaced" even before Meghan Markle entered the picture.
