'Sister Wives' season 7 cast rumors: All 4 wives 'miserable' and leaving the show?

For a while now, rumors have been flying about that three out of the four wives of polygamous husband Kody Brown will opt out of "Sister Wives" season 7, but it is only today that a family member speaks up about the possible exit of not just three but all four wives.

Kristyn Decker, aunt of "Sister Wives" star Christine Brown and who also happens to be a former polygamous leader, told Radar Online that "There is a lack of connection between the women. They don't know where to stand when they're talking about their relationship with the other women."

"They don't get the quality time they want with their husband. Neither do the children. The spousal connection isn't there. They are happy because they believe they are serving God, or their God. But it is miserable happiness," Decker described.

"Sister Wives" fans will remember that Kody's former legal wife Meri fell victim to catfishing after allegedly feeling lonely and alone. Janelle, on the other hand, is said to focus on her career in real estate and will be sitting out "Sister Wives" season 7 while Christine, according to Decker, is just not happy and is "miserable."

As for Robyn, who recently welcomed her second child with Kody, Decker believes that the polygamous relationship is not working out for her too. It has always been said that Kody's new legal wife will be the star of "Sister Wives" season 7 but if Decker's claims are any indication, this won't be the case.

At the moment, TLC is yet to make "Sister Wives" season 7 official. However, by the end of season 6, it was hinted at by "USA Today" host Tamron Hall, who was also the host in the season 6 tell-all special, that "Sister Wives" season 7 will be all about Robyn and Kody's new baby.
