Bachelorette Star Katie Thurston and John Hersey Break Up: 'The Decision Was Not Made Lightly'

Katie Thurston and John Hersey have called it quits.

The couple announced Monday that they had broken up. The split comes 15 months after the pair met on The Bachelorette, though their romance blossomed off camera when filming for the series concluded.

Each spoke out about their breakup on their respective Instagram Stories. "Statement: no we aren't together," Thurston, 31, simply wrote in her post.

Hersey, 28, was more verbose. "As Katie stated earlier, we are no longer dating," he began. "The decision was not made lightly and it was obviously not an easy one to make."

"I love being able to share special moments with you all — the funny ones. The happy ones. The outrageous, embarrassing, and heartfelt ones. But I don't know if it will ever get easier to share the sad ones," he also said. "I appreciate every one of you that has supported us throughout this journey. We could not (and would not) be here without you."

The two shared much of their relationship on social media with PDA-filled posts, including one in January when Thurston revealed that she's the "happiest version" of herself with Hersey.

"Falling for you was the best decision I never had a say in, and I couldn't be happier," Hersey said that same month. "I could have never dreamt up what this year had in store for me. I am both in awe of, and extremely grateful for the circumstances that brought us together. And thank goodness you dumped me on national television, or else we could have never gotten to where we are now."
