Caroline Wozniacki has opened up about her split with golfer Rory McIlroy, admitting that the call to end their engagement came as a "shock". The tennis star spoke about their high-profile break-up in an interview with The New York Times, saying that his decision to call off their engagement just days after sending out invitations to the wedding left her questioning their relationship.

“When it comes out of the blue, that’s like a shock. It’s like someone dies right in front of you," she said.

“You start thinking what was wrong? What went wrong?”

Wozniacki's friend Serena Williams revealed to the newspaper that Caroline had told her "I could never hate him. He’s been a big part of my life and even if I wanted to, I couldn’t hate him".

However, while she does not seem to be holding a grudge, the 24-year-old said that she has not spoken to her ex-fiancé since that break-up phone call, adding "I don’t follow his life and I don’t really follow golf anymore".

"I don’t believe in holding on to someone who doesn’t want to be with you. I definitely want someone who just wants you for who you are. I’m very upfront, I’m very honest and I’m very straightforward and I think some people get intimidated by that. I’m not saying Rory did...”

“In general, a lot of people do, and if I’m in a relationship that’s strong, I’m the person I am and that’s exactly what you get.”

She also told the newspaper that she was "happy being single right now" and had learned "what I want out of a relationship in the future and what I don't want".

“I don’t want to have my name stuck with him forever. I’m my own person. I have my own career. The years we had together were great, and unfortunately, things had to end like they did.”

"It’s important in relationships to talk. If there’s a problem, you talk about it. That’s normal. Obviously, I didn’t have that chance. At the end of the day, I couldn’t have done anything different. I couldn’t have done anything more. I gave everything I had. And if that’s not enough, that’s fine. I’ll find someone who will.”
