The other girl's questioned Brooke not telling the other girls Brittany and Sophie.
Brooke said, “He told me not to tell anyone and I protected him”.
“I couldn’t tell the other girls and I felt that was really sh*t,” she admitted. “I don’t regret the decision to leave. I don’t want to be with someone who’s not committed. I’m not going to waste my time and I feel like that’s what he did to us.”
When speaking to producers, Brooke revealed Nic “pretty much just broke my heart and made me feel like I have to keep the secret”.
But, former Bachelor co-star Brittany Hockley has spoken out against Brooke's claims.
"It's in the past," she added. "There's no point in bringing it up. I would personally never go into it but Soph and I were told something very different."
Following the episode's airing, Nick responded to fans via Instagram. One person wrote underneath his latest photo that he should "turn off his comments" after several people had left angry opinions.
Nick wrote, "Don't hide from life mate, own your decisions".
