Khloe Kardashian doesn't believe in divorce, says she's still honoring vows to Lamar Odom, God

Khloe Kardashian penned an essay about her Christian faith for Lena Dunham's Lenny newsletter, and shared her views about divorce.

The 31-year-old reality star filed for divorce from Lamar Odom -- who she married in 2009 -- in December 2013, but it has yet to be finalized. "I've been blessed with a lot in my life, and I’ve also had challenges," she writes. "It was a challenge for me when I decided to get divorced."

Khloe admits that she never wanted to dissolve her marriage. "At my core, I don’t believe in divorce," she continues. "But I came to a point in my marriage where I had to make the choice to take care of my own mental and emotional well-being in order to protect myself and my happiness."

The "Keeping Up With the Kardashians" star adds that she feels she did everything she could do to make her marriage work. "I am at peace with that decision and do feel like I honored my vows to the very end," she insists. "I feel that I kept the serious vows I made in front of God with every inch of my heart, which is why I am still honoring them today even though my relationship with my ex-husband is in a different place."

In October 2015, Khloe called off her divorce after Lamar, 36, was he found unresponsive at the Love Ranch brothel in Crystal, Nevada. Now that the former NBA pro has recovered, a source close to Khloe told ET in April that she plans to move forward with the divorce.

"I believe in caring for my partner -- past or present -- 'in sickness and in health,'" Khloe explains. "And feel at peace with my relationship with God even after the fact. I’m thankful that I can rely on my God, who, along with my family, has led me through some of the most difficult times of my life."

Prior to the release of Khloe's essay on Tuesday morning, Dunham and Lenny co-creator Jenni Konner told ET's Jen Peros at the Webby Awards in New York City on Monday that the "female Drake" had contributed to their newsletter. "One of our major dreams is coming true," Konner said. "We're really excited," Dunham added.

In April, Lamar opened up to ET about going forward with divorce proceedings with Khloe. "We did talk, you know, everything is [up for] discussion," he said of his ex. "We talk about anything. We've been through a lot. It won’t ever stop."
