“Once I had the conversation with Cassie, my mind was made up. I was either going to leave by myself, or I was leaving with her,” he shares.
And after the infamous fence jump, Underwood, 27, was able to collect his thoughts, and realized he needed to break up with both Adams and Godwin in person.
“I had to do what was right, and what was best for them, and that was to have that tough conversation,” he says.
And ultimately, “the game was changed in a way,” Underwood reveals.
“I knew I could walk away heartbroken,” says the Bachelor star. “But I had to fight for Cassie.”
Part 2 of The Bachelor‘s finale airs Tuesday at 8 p.m. ET on ABC.
