It appears even the wife who was reportedly most devoted to her marriage to Kody Brown has decided to throw in the towel on her relationship on Sister Wives.

According to reports, Robyn Brown is also preparing to find a way out of her marriage to Kody, something she needs to handle with care since becoming his only legal wife almost two years ago.

Her alleged friend Kendra Pollard, told Life and Style (via IBT) that Robyn is working on a plan that allows her to divorce Kody, and she's been quietly meeting with attorneys to see how she can pull the plug after she's financially secure and can move to Northern California after it's done.

According to Pollard, Robyn was "let down" by Kody because she had been under the impression that she would eventually become his only wife, and that didn't happen.

"She did not want to be in a polygamist marriage," Pollard said, saying the goal Robyn had was to get Kody to eventually part ways with Meri, Janelle and Christine, who he is also on the outs with.

However, the real kicker is that Kody allegedly made awful comments to her after she gave birth to their daughter Ariella in January.

"He told her, 'You used to be considered the hot wife. Unfortunately, we can't really sell that anymore,'" Pollard claims.

But even if Robyn leaves, she may still be considering a career of her own in reality TV, especially if the family's show doesn't get renewed any more after the season which premieres later this month.

"She's seeking a spinoff," Pollard said. "She's pretty close to the team that oversees Sister Wives production and she's told them, 'You can follow me anywhere I go.' She's very open about it."

Sister Wives season 8 premieres Nov. 27 on TLC.
