Becca, however, was successfully able to make tough decisions because she said she had "a moment of clarity" at the end of each week, ultimately leading her to her final pick.
"It was a sense of something I can't even describe. It was a feeling right in my heart," Becca said, later adding, "I listened to my head and tried to stay logical to a certain degree, but I also just had to follow my heart."
The 28-year-old publicist revealed earlier this week she's engaged, and she apparently couldn't be happier about her choice.
"[I love] so many things [about him]. So many things," The Bachelorette star sweetly said. "Just that he put up with me through the entire journey."
When asked to compare her new relationship to what she had with Arie, Becca responded, "It feels so different because the relationship and the guy is different."
"And this time," she continued, "it feels better suited for me. It's like this better fit for me and what I need in my life. I am willing to do anything it takes to make it work to support my partner."
Both Becca and her mystery fiance sound lucky, because she apparently believes they are a perfect match, destined for a life of happiness.
"I was asking for a teammate, a 50/50 [partnership] throughout the entire season. I feel like I truly found that," she gushed.
"So we'll have each other's backs through the time where we have to stay private. And then we'll continue that and share it with the world. I better [marry him]! He better marry me."
