Prince William didn't want Prince Harry to marry Meghan Markle in 2018

Prince William was reportedly against Prince Harry and Meghan Markle’s whirlwind romance before their 2018 royal wedding, with royal expert Tina Brown citing several sources saying that the future King worried for Harry’s mental state.

Brown, the author of several books including The Palace Papers: Inside the House of Windsor, spoke to more than a 100 Palace sources and claimed in her book that Harry battled several demons before Meghan entered his life.

Harry reportedly struggled with his temper, that had also led to the end of a long-term romance with Cressida Bonas, and when he met Meghan, Prince William reportedly felt that Harry should give her more time to adjust into the royal life in the UK.

Brown stated in her book: “A person close to the Duke of Cambridge told me that William thought she should have more time to build up a life in the UK and make friends who didn't always have to be brought in confidence to the palace.”

She further shared: “Unspoken to Harry, the person said, was the older brother's fear that Harry's mental fragility was such that he wouldn't be strong enough to handle all of that on her behalf, as well as his own issues.”
