“It was heartbreaking,” Brown says through tears. “The foundation of what I believe love is is based on honesty and truth. If he loved me, wanted the best for me, why did he not give that to me? He always said he never wanted to hurt me, but he hurt me worse than anybody else did.”

Continues Brown: “I did feel remorse from him, but I still think he tried to justify that [relationship].”

Brown says she was totally unprepared for the bombshell, despite what many perceived as red flags on the show, including when Wyatt himself admitted that he applied to further his music career.

“I was really insecure,” explains Brown. “I knew that no guy was actually there for me because they didn’t know who the Bachelorette was going to be. And I was the dark horse. So, Jed being honest [was] refreshing. He didn’t come for me, but he liked me. And that’s what made me initially start to fall for him.”
