The 49-year-old announced on Tuesday, November 2, that she and her husband of 25 years had called it quits.
"He was devoted to being polygamous so he kept that going for as long as he could," the insider explained. "He serves God and believes being polygamous is his way to heaven, so it’s not necessarily about having to be in love with all your wives. It’s about who else is as devoted as he is."
According to the source, the former flames "do not get along."

"[Christine’s] really hurting. She really loved Kody. She gave him her all in hope that he would love her," the source spilled. The insider noted that the coronavirus pandemic also played a role in the split.
"Kody has not been around at all," the source explained. "He used COVID-19 as a big excuse to not be around family. It’s been his ticket to freedom essentially. This destroyed Christine because she really tried to give her all to the marriage."
"Christine’s decision to leave comes with a great deal of sadness," Kody shared on Instagram. "We enjoyed many years together and I have a large amount of respect and admiration for her. Although we are moving forward on different paths, we will always remain committed parents."
Kody and Christine tied the knot in 1994. He married Meri Brown in 1990 and Janelle Brown in 1993. Kody and Meri legally divorced in 2014 so he could marry Robyn and adopt her children.
Kody and Christine share children Asypen, 26, Mykelti, 25, Paedon, 23, Gwendlyn, 20, Ysabel, 18, and Truely, 11.
