Arie Luyendyk Jr. got engaged to one woman in the finale of "The Bachelor" season 22, only to break up with her weeks later.

Next week, the former race car driver will finally reveal who will win between the final two women he chose. ABC has released a new teaser for the finale and he admitted in the clip that he has "found love" with both contestants. Becca Kufrin and Lauren Burnham are the two women left competing for Luyendyk Jr.'s love, and he is obviously having a hard time choosing between them.

As many fans already know, "The Bachelor" is filmed in advance so Luyendyk Jr. certainly had to make a tough decision when he gave the final rose. Us Weekly reports he proposed to one woman at the end of season 22, but he ended the relationship with her just weeks later. Within days after calling off his engagement, the ABC celebrity traveled by plane to profess his true feelings to his runner-up.

"Arie had a change of heart," an insider on the show told the media outlet. "He began to think he'd picked the safer option."

Of course, his unexpected betrayal will lead to one of the most dramatic conclusions in the franchise's history. The 36-year-old recently teased that the final episode of season 22 is not one to miss. "The finale is going to be very interesting for fans to watch," he shared. "It's been an experience I'll remember forever. It's going to be fun for me to watch back."

Luyendyk Jr. is not the first Bachelor to break up with the woman he's engaged to and eventually date the runner-up. Nearly ten years ago, the entire Bachelor Nation was shocked when Jason Mesnick called it quits with Melissa Rycroft on live TV during the "After the Final Rose" special after popping the question in the final episode. He explained at the time that he was actually in love with Molly Malaney, who he asked for a second chance after splitting with Melissa.

The final episode of "The Bachelor" season 22 airs on Monday, March 5, at 8 p.m. EST on ABC.
