Prince William, Prince Harry, and Kate Middleton were famously inseparable at one point. But the brothers had a falling-out, which Harry's book "Spare" describes, and their emotional and geographical distance still keeps widening. William and Kate have especially struggled this year since Kate is fighting cancer and Charles also cope with his own diagnosis and treatment. Kate seemed remarkably at Wimbledon despite these challenges, implying she is healing.

The Mirror claims William and Kate have made deliberate decisions about Harry. They decided not to see him during his most recent trip to the United Kingdom in May for the 10th Invictus Games. William and Kate's decision was inspired by their emphasis on rehabilitation and optimism, according to a source. Though Harry had gone to London shortly following his cancer diagnosis in February, Charles did not meet him during this visit either.

William was sensitive and orderly, according to royal biographer Ingrid Seward, who also noted that his troubled relationship with Harry affected him more than he acknowledges. Seward said William would sooner withdraw himself than deal with continuous irritation.

William is quite protective of Kate since she is still undergoing treatment. William has never been more protective of his family, according to former BBC royal correspondent Jennie Bond. Working closely with Diana, former royal butler Paul Burrell claimed that Harry cannot enter Adelaide Cottage, William and Kate's house. William apparently wants to prevent more family problems as Harry seems unreliable.
