Christine Brown of Sister Wives has always been known to be the joyful wife, but there have been a few times her jealous side emerged, causing viewers to think that the personality trait could have driven Kody Brown away. The patriarch is struggling to keep control of his sizeable polygamous family as his wives seem to be turning on him. Now, fans are noticing the green-eyed monster sneaking out more and causing major issues.

Christine and Kody have been married since 1994, and they have had their fair share of ups and downs throughout the years. Christine was introduced as the third wife of Kody, and the blonde truly believed she would be the last wife. Christine noted how she liked that spot since she felt like the most desired of all the wives. The couple's marriage has been on the rocks for some time, and the Sister Wives season 16 trailer has shown Christine unhappy. Christine has made it known she wants to move back to Utah and leave Arizona behind. The TLC personality revealed recently she sees no point in continuing her dysfunctional relationship with Kody.

Christine's jealousy has often been a central storyline on the series. Fans will recall she used to refer to the other three wives as "baggage." To many fans, Christine has always envied the woman who held the number one spot. First, she had issues with Meri, and then she set her sights on Robyn, who everyone agrees is favored by Kody. Christine has been able to keep her resentment close to her chest, but her evil twin appears every so often. The third wife has now turned her sights on Robyn. Recently, Christine posted her love for jeweler Kendra Scott. She shared tons of information with her followers while completely shading Robyn's own jewelry line.

Christine's passive-aggressive attitude could have easily turned Kody off. Sister Wives fans have watched her become more demanding over the years. TLC viewers will recall that during season 10 Kody and his wives sat down to air out their grievances with one another. The four matriarchs of the family met up for the first time in months and openly spoke about how the physical divide had affected their "culture as a family." Christine was the most outspoken in her confessional when she revealed she had been feeling very isolated. Perhaps her neediness turned into jealousy, leading Kody to want nothing to do with her.

This newest season will show the Brown family tensions running high. The pandemic outbreak has also not helped the family since each wife chose to follow their own rules. The Sister Wives could very well be on the verge of losing their once-proud family. As for Christine, she seems to have walked away from her husband with no looking back. Only time will tell if she pushed Kody away for good.
