Khloe Kardashian: Filing For Divorce 'Is Something I Thought I'd Never Have to Do'

March 10, 2014 -- It's a good thing Khloé Kardashian has her sisters to lean on.

In yesterday's episode of "Keeping Up with the Kardashians," the 29-year-old reality star opened up to her older sisters Kim and Kourtney about the struggle she faced while deciding whether to file for divorce from Lamar Odom.

"It's something I thought I'd never [have] to do," she tearfully told her sisters. "It's not fair that like, this is even something that I think anyone has to go through."

Kim, 33, pointed out that Khloé had been doing "every last thing a person can do," including showing up to couples therapy sessions that Lamar skipped.

"You don't have to go through it alone. That's why we're here," Kim said. "We know it's hard on you. It's the hardest thing, but you've told him, 'Come fix this marriage.'"

However, Khloé didn't think that Lamar understood the consequences of his actions, which only made her feel more guilty about pulling the plug on their relationship.

"I don't think he understands and that's what's so hard. I've said, 'OK. Like, do you understand, if you keep not showing up to therapy then I'm done. I'm gonna file,'" she said. "The saddest part is when you do that and it doesn't even rattle the person. When I threaten it, and no one even blinks an eye."
