The truth behind why Christine, Meri and Janelle Brown left their plural marriage will be revealed on ‘Sister Wives’ season 18

Sister Wives is returning with even more details on how Kody Brown ended up a one-wife man.

A new trailer for season 18 shows Janelle Brown speaking about her decision to leave the plural marriage. It all starts with Kody telling her, “You have cheated me out of my family.”

Janelle responds with anger. “You are now pushing me out the door,” she says. When Kody denies this, she adds. “I think you’re manipulating.”

Harsh words and a door slam are exchanged when Kody bolts to leave. “You stay and talk,” Janelle says. When Kody ignores her, she says, “f— you.”

Christine Brown also shares a little more about why she decided to leave her spiritual marriage behind. “I left Kody cause I could see he had favorites,” Christine says, while a clip plays showing Kody stroking wife Robyn Brown’s back.

Even Meri Brown admits, “I’ve heard [Kody] refer to us as friends,” instead of his wives.

Season 17 of Sister Wives ended with an explosive One on One episode, which announced both Janelle and Meri had stepped away from the plural marriage. That left Kody with just Robyn left — as his plural marriage became unintentionally monogamous.

Since, Christine has found love with someone new. She accepted a proposal from David Woolley earlier this year, and the pair are already planning their wedding.

Despite the distance — and complicated family dynamics — Kody and his wives (both past and present) reunited at daughter Gwendlyn Brown’s wedding to Beatriz Queiroz in mid-July.

Season 18 of Sister Wives premieres Aug. 20 at 10 p.m. ET on TLC.

Sister Wives’ Janelle Brown Tells Kody ‘Don’t You Dare Point Your Finger at Me’ as Marriage Breaks Down

“I’m growing and I need something different, like I don’t want to be married anymore,” Janelle Brown says in the trailer for the upcoming season of ‘Sister Wives’

Janelle and Kody Brown are facing the end of their marriage in the upcoming season of Sister Wives.

In a preview of the TLC hit’s 18th season, Kody admits he is in a “bad place” with Janelle. She asks, “Do you really still want to have a plural family? Sometimes I can’t tell.”

With tensions rising between the pair, she tells Christine — who announced her split from Kody in November 2021 — that she is ready to move on, explaining, “I’m growing and I need something different, like, I don’t want to be married anymore.”

Later in the clip, Kody and Janelle, both 54, have an explosive argument when the Brown family patriarch questions what partnership they have left.

“This is not only me, Kody,” Janelle says. “Don’t you dare point your finger at me!”

“You make this excuse forever but I’ve tried…” Kody responds. However, she wasn’t ready to hear his side of the story, saying, “Shut your f—ing mouth and let me talk to you for a minute.”

“No, no, no. I’m done listening to you,” Kody replied before storming off the couch.

“Ok. So, we’re done?” Janelle asks and he adds, “Goodbye.” Her anger flares and she says, “F— you” as he slams the door shut.

Janelle announced her separation from Kody in December 2022.

“Kody and I have separated and I’m happy, really happy,” Janelle told host Sukanya Krishnan on Sister Wives: One on One special in January. “I don’t know, things just really became sort of indifferent, like I just didn’t care anymore.”

Janelle also said that she was “not waiting” for a possible reconciliation with Kody. “I’ve kind of mourned that that part of our life is gone,” she shared. “I wasn’t heartbroken. It wasn’t heartbreaking for me like it was for Christine [Brown]. It was just kind of like, I just mourned that that life was gone…. We had this great run.”

Christine, 51, left the plural marriage in 2021, and Kody also confirmed his separation from Meri Brown, 52, during the One on One conversations and later in a joint Instagram statement with his ex. He is now only married to fourth wife Robyn Brown.

Since her split from Kody, Janelle has been documenting her “independent woman” summer on social media and sharing motivational messages with her followers.

Kody and Janelle recently reunited for daughter Savanah’s high school graduation. The former pair share children Logan, 29, Madison, 27, Hunter, 26, Garrison, 24, and Gabriel, 21.
