John Cena is slowly opening up about his split from fiancée and girlfriend of six years Nikki Bella. “I love Nicole with all my heart and the split’s tough,” he said on the red carpet while promoting Bumblebee at CinemaCon in Vegas.

The couple announced their decision to part ways earlier this month. “It’s a tough time, but that’s life,” Cena said. “We all go through highs and we all go through lows. I’m gonna get through it. I love her. I’ll always love her.”

Cena proposed to Bella during WrestleMania 33 back in 2017. Last month, he was publicly discussing the wedding planning process. “I am super excited, and I’m going to have to learn a dance. I promised Nicole that I would spend the last half of April learning a dance,” he told Jimmy Fallon during a Tonight Show appearance in March.

The split came only weeks before their planned May 5 wedding date. “While this decision was a difficult one, we continue to have a great deal of love and respect for one another,” the pair said in a statement tweeted out by Bella. “We ask that you respect our privacy during this time in our lives.”

A source close to the situation previously told People that Nikki pulled the plug on their wedding. “John acted more and more like he was doing her a favor by somehow conceding to go ahead and marry her,” the source said. “[Nikki] doesn’t need a pity proposal, a pity wedding, a pity husband. She’s a phenomenal, tremendous woman.”

“The fact that my heart hurts for her…I know I was in love,” Cena said at CinemaCon. “So, I’ll always have that.”
