He is now only married to Robyn. "I think a part of them would always be a little bit sad that this didn't work and that the big family didn't work," says Christine, 50. "And I think that there'd be a little bit of a mourning and a little bit of a loss there still, because it's a dream, right? It's giving up on a dream, and it's not a dream that they wanted to give up on, necessarily." Christine then adds, "I don't see them looking for another wife after this."

"If you already have this much failure behind you, would you really want that again?" she asks. "And if they're just happy with each other — and I perceive them as being soul mates with each other, is there room for anyone else, really?"

Sister Wives' Robyn Says She's an 'Easy Target' in Brown Family: 'I Have a Tendency to Just Take It' Christine was the first to leave her polygamous arrangement with Kody, 53, in November 2021. She has since moved to Utah with the pair's youngest child, Truely. Nearly one year after Christine left, Kody's separations from Meri, 50, and Janelle, 53, were made public during the first installment of Sister Wives: One on One.

Because I have a tendency to just take it. And just not get jerky about it," she said in a previous Sister Wives: One on One episode. "I don't fight. It's not my nature to fight. I have to really, really get tough within myself to fight. I'm just absolutely more heart."
