PGA golfer Rory McIlroy said on Wednesday that he has broken off his engagement to tennis star Caroline Wozniacki, his longtime girlfriend.

McIlroy, 25, ended the relationship just days after the invitations for the couple’s November wedding went out in the mail over the weekend. The two-time major winner addressed the split in a statement released on Wednesday.

“The problem is mine,” McIlroy said, via the BBC. “The wedding invitations issued at the weekend made me realize that I wasn’t ready for all that marriage entails. … There is no right way to end a relationship that has been so important to two people. I wish Caroline all the happiness she deserves and thank her for the great times we have had.”

McIlroy stressed that the decision to break off the engagement was mutual and insisted that he and Wozniacki, who is 23, remain cordial.

The athletes were engaged on New Year’s Day after McIlroy proposed shortly after midnight in Australia,  USA Today’s "For The Win" noted. In a recent interview with Global Golf Post, McIlroy said that his proposal was nearly ruined by a drunken bystander.

“We were on a boat on the harbor. It’s a funny story because I wanted to do it at the stroke of midnight but I couldn’t because a really drunk guy on the boat jumped in and caused a whole commotion. […] It was a bit of a nightmare,” he said.

McIlroy’s engagement to Wozniacki isn’t the first time that an athlete’s relationship came to an end in public fashion. Here’s a roundup of nine of the nastiest sports breakups of all time.
