In an interview, Moriah, 21, notes that things have seemingly gotten “worse” with Olivia, 25. The two were previously best friends, but appear tono longer be on speaking terms. The tension between them has only increased as Moriah hasgrown closer withher parents again.
“Olivia hassaid a bunch of things about my parentsfor years, and it’s onlygotten worse,” she says in a confessional. “It’s gotten to the point where lies are being told. And I personally want to do my part in making things right.”
Moriah brings up the"credit card story"as an example, referring to Olivia’s allegation that Kim stole money from Ethan. “The way I see that is, she was using, basically, a made-up story to validate her big emotions,” she says.
She adds that she understands and accepts how Olivia feels about her family, but she simply refuses to tolerate her “lies” any longer.

“You have every right not to like a person that’s okay. And you have every right to be like, ‘Their values or their beliefs or whatever, don’t line up with mine and I don’t want to associate with that,'” she continues. “That’s okay. But it’snotokay to try and make the whole world or a whole family feel the same way.”
Barry agrees with his daughter’s assessment and calls Olivia’s behavior “relationally destructive.”
“I see that now,” Moriah says. “And that’s why I choose not to have a relationship with her anymore.”
