Sister Wives star Kody Brown may have invested everything in his marriage to Robyn Brown, but without his other wives in plural marriage, his relationship with her is crumbling quickly. Kody, who has been married to Robyn legally since 2014, was living in plural marriage from his early 20s. Marrying his ex-wife Meri Brown in 1989, he brought Janelle Brown into the fold a few years later, followed by Christine Brown. Kody’s began to break down quickly in the late 2010s. Christine decided to spiritually separate from Kody in 2021, and was followed by Janelle and Meri in 2022.
