Kate Middleton was desperately upset after Prince William broke up with her.

According to royal correspondents Laura Collins, Katie Nicholl and Ian Gallagher, Prince William split with Middleton while they were still in university because he felt that the “fun” was gone. Middleton was reportedly left “desperately upset” because she had always believed that they would marry, Express reported.

Middleton made several sacrifices for Prince William. In fact, she was dubbed “Waity Katie” because it took too long for Prince William to propose.

According to Nicholl, Middleton has always been a model of what a princess should be because she is patient and loyal. And so she was very upset when Prince William decided to break up with her.

To make matters worse, the duchess felt humiliated after Prince William was seen gleefully telling a group of seven friends, “I am free.”

The second-in-line to the throne was also photographed dancing in a podium in Bournemouth next to a pretty Brazilian girl. The duke’s photos were splashed across every newspaper and Middleton was not happy about it.

“But after his recent behavior, she gave him an ultimatum and told him that over the time he behaved like that in public he was cheapening her image as well as his own,” an alleged friend of Middleton’s said.

“She told him she wasn’t prepared to be treated like a doormat and that his carefree behavior was affecting her image,” the friend added. “In the past, she had always let go of things like that, but this really bothered her.”

Prince William refused to get back with Middleton after he dumped her. He started missing his then-girlfriend and was lonely, but he didn’t reach out to get back to her. He even went to a cinema to cheer himself up.

Even Prince William’s friends noticed how he missed her. The future king eventually realized his mistake and decided to get back with Middleton. Since then, they never split again.

During their engagement interview, Prince William and Middleton spoke about their split. According to Prince William, they parted ways because they were still figuring out what they wanted in life back then.
