The Duchess of Cambridge is the newest speculated reason as to why Prince Harry and Cressida Bonas broke up after two years.

Prince Harry and Cressida Bonas Still 'Best Friends'?

An insider close to the whole ordeal said Sunday that Kate Middleton advised Bonas to take a break from her relationship with Prince Harry and all of the pressures of being a potential for the royal family, just as she did with her now husband, Prince William back in 2007.

"Kate feels for Cressie. There's an awful lot of pressure when the whole nation is asking if you're about to get engaged. So she told Cressie how she benefited from taking time out when she was on a break from Wiliam. Kate said it might be best for them too."

Prince Harry Texts Cressida Bonas 15 Times a Day?

Still, rumor has it that Middeton was never really a fan of Bonas to begin with since Bonas' half-sister used to date Prince William.

A separate source said that while they have decided to call it quits for now, Bonas still has love for her on-again-off-again boyfriend.

"Cressida loves Harry but sadly she was really struggled with the demands of dating a prince. The vast attention Cressida received after that first public engagement was a real eye-opener."

This isn't the first time Middleton is said to have had a say in Prince Harry and Bonas' relationship. When reports were circulating that they were getting ready to call it quits, a insider said Middleton stepped in and encouraged him to not let rumors get out of hand.

"Kate knows all too well how damaging false reports can be. So she urged them to show the world they were still going strong before they story snowballed."
