The Bachelor‘s Arie Luyendyk Jr. Explains That Heartbreaking Twist

So why did he pop the question in Peru if he felt so conflicted about his final choice?

“I didn’t want to let anyone down. But I needed more time to make that decision. I made a huge mistake,” he says. “I went with my head, and I shut down those feelings for Lauren. The relationship with Becca was great, but my heart wasn’t with her.”

Confused about his emotions, Luyendyk Jr. sought the advice of people who’d been in his position before.

“Immediately after the proposal, I just had this hole in my heart. I tried to concentrate on my relationship with Becca, and I really made a push to make it work.But I wasn’t getting over Lauren,” he says. “I leaned on former Bachelors and Bachelorettes, like Rachel [Lindsay], JoJo [Fletcher], Sean [Lowe], and asked them, ‘Is this normal?’ Everyone was like, ‘Yes, give it some time.’ I was very open with Becca about how I was feeling. It must not have been easy for her. But I knew that it was more than just missing someone. I had to take this risk.”
