Becca felt drawn and pulled to Colton, and she was very attracted to him, but she struggled to get over the fact he had dated her good friend.
"I was truly conflicted in the decision to keep Colton and I remember making myself sick over the potential to jeopardize my friendship with Tia," Becca wrote in her blog, referring to how Colton received the last rose at the ceremony during the latest episode.
"I made the decision to keep him one more week but not feed anymore into our relationship until I was able to speak with Tia -- you'll just have to wait and see."
As previews for the next episode show, Tia is going to make an appearance at the Los Angeles mansion for a spa-day group date with several of Becca's other friends, including Bekah Martinez and Caroline Lunny.
The men will apparently be responsible for the ladies' spa services, such as manicures and pedicures.
However, a day of good fun is eventually going to lead to some tears and tough choices for Becca.
"One goodbye leaves me absolutely heartbroken," Becca revealed, "and the tension continues to build between two guys, leaving one of them in a pool of blood."
The Bachelorette star concluded, "You'll have to wait... to see everything unfold and how my relationship with Colton takes an unexpected turn and what this ultimately means for my friendship with Tia."
