Meghan Markle and Prince Harry’s exit from the royal family may be what’s best for the couple, but the split has reportedly left Kate Middleton feeling hurt by the effect it has had on her relationship with her brother-in-law.

Earlier this month, the Duke and Duchess of Sussex announced their plan to “step back” from their roles as senior royals. Although Queen Elizabeth released a statement claiming the royal family supports the couple’s decision, insiders believe Kate is torn up over the arrangement.

Sources told Us Weekly the Duchess of Cambridge is struggling to deal with her new responsibilities following Meghan and Harry’s exit. “She barely has time to rest, and when she does try to sleep, her mind is constantly racing,” an insider explained.

The source revealed the 38-year-old mother of three sometimes works as long as 18 hours a day. “She’s already stretched pretty thin, and now, she’s really worried about how she’ll juggle the extra workload on top of her family life,” the insider continued.

Along with her royal duties, Kate is also a mother to Prince George, 6, Princess Charlotte, 4, Prince Louis, 1. The source went on to claim that Kate is worried that the couple’s relocation to Canada will destroy her relationship with Prince Harry.

“She wishes she could speak to Harry. She misses him and fears she’ll never be close to him again,” the confidante revealed.

Harry and Meghan are expected to split their time between the UK and North America. However, the couple has been reportedly house-hunting in Canada.

“After many months of reflection and internal discussions, we have chosen to make a transition this year in starting to carve out a progressive new role within this institution,” the couple said in a Jan. 8 Instagram post.

“We intend to step back as ‘senior’ members of the Royal Family and work to become financially independent while continuing to fully support Her Majesty The Queen.”

Meghan and Prince Harry are expected to officially step back from their royal duties in spring 2020.
