Prince William and Kate's marriage is reportedly going through a rough patch.

The release of Prince Harry's memoir, "Spare," is said to be the cause.

The book revealed stories about the royal family, including Prince William and Kate.

Kate allegedly feels that William should have stood up for her more.

The couple reportedly had serious arguments and resorted to name-calling and door slamming.

They have been seen hand in hand in public since the book's publication.

A royal author wrote that William and Kate are constantly surrounded by palace aides.

Harry claimed that William pushed him to the floor during an argument about Meghan Markle.

Harry also said that William was parroting a "press narrative."
