Mark confirmed in the Monday episode of his "Find Your Fortitude" podcast that he and Elena, who met on Big Brother's nineteenth season and began dating in September 2017, are done, Us Weekly reported.
Mark allegedly recorded the broadcast about two weeks after the couple had called it quits on their relationship.
The 27-year-old fitness trainer apparently struggled to deal with Elena speaking ill of him and their relationship on social media as well as in her own podcasts.
"I was happy when she was happy," Mark said, according to Us.
"It was really that simple for me. I was happy when she was happy. And so, with that mindset and perspective, hearing constantly that it's not a fairy tale and I'm far from Prince Charming, it was just a gut shot."
Following their stint on Big Brother, Mark followed Elena, 28, to Texas because he fell in love with her.
Mark reportedly said on his podcast the goal was to "start a family" and "start a life" with the bubbly blonde.
But on February 27, Elena wrote on Twitter it was "unlikely" fans would see her with Mark again, alluding to their break up.
"But you might find me alone at the local bar," tweeted the radio personality.
