Because of the laws in the United States, Kody Brown can only legally be married to one woman at a time. So, for most of his plural marriage with Meri, Janelle, and Christine Brown, he was only legally married to Meri (via The Sun), while he had "spiritual marriages" with the other wives. However, when Robyn Brown came along, things got even more complicated: Robyn was previously married to someone else, and actually had three children of her own (via In Touch Weekly). To help make things easier, Meri agreed to divorce Kody so that he could marry Robyn and legally adopt her children, bringing them all into their big family.
Of course, that was a big sacrifice for Meri to make. But in a tell-all episode of Sister Wives, Meri explained she felt confident in her decision (via Good Housekeeping). "It's an end of something that we had had, in a way, for 24-and-a-half years," she revealed. "But at the same time, I know it's not, because I have eternity with him; I have eternity with the family." After that, it's clear that Meri loves Robyn.
