The cracks are becoming bigger and more prominent in Kody Brown's polygamous family. Reports state that Kody's spiritual wives, Meri, Janelle and Christine, are finally fed up with their husband's selfish and bullying ways and are getting ready to leave.

Fans of "Sister Wives" should brace themselves for more drama and tension in season 7. There have been reports that the new season will focus more on Kody and his new legal wife, Robyn, and her children. As regular viewers know, the Brown patriarch's adoption of Robyn's three children from a previous marriage was legalized last season.

Viewers might also be in for a surprising turn as the other sister wives are reportedly set on leaving Kody. The news appeared on Radar Online, which reported that the three women have had enough of their husband's bullying ways.

An insider allegedly revealed that the Browns do not exactly have "the loving polygamist marriage people see on TV." There have been hints that Kody's wives have not been content with their unusual situation for a while now.

The previous season of "Sister Wives" saw Kody's first wife, Meri, become a victim of catfishing--something that she had attributed to loneliness in one episode. She had also complained of her husband just doing whatever he feels like.

Christine and Janelle have had issues with Kody as well. The insider added that 47-year-old Kody fat-shames his wife, Christine, and had even had strong words to say about her looks when he first met her. The couple even went through their own version of marriage counselling in season 6. Other reports say that Christine is still questioning her place in the family dynamic. Meanwhile, his first spiritual wife, Janelle, has reportedly been unhappy in her marriage for a long time now.

However, it seems that Kody's new wife, Robyn, is quite happy with her marriage and season 7 will reportedly focus on the pair's relationship as a married couple. Viewers will recall that Meri, Kody's then-legal wife, divorced him so that he could marry Robyn and adopt her three children from her first marriage. But it seems that Kody has been spending most of his time with his new wife and neglecting the others.

"Sister Wives" season 7 is expected to air in 2016.
