Kim Kardashian broke down in tears while discussing the difficulty of co-parenting with Kanye West during an interview

Kardashian shares custody of four children with ex-husband West: North, 9, Saint, 6, Chicago, 4, and Psalm, 3.

The public spectacle of the couple's divorce has put a lot of unwanted attention on Kardashian's relationship

West, she said, but she told Martinez that she's trying not to vilify him. "One day my kids will thank me ... for not bashing their dad," she said.

Kardashian said she is putting on a brave face for the world, but it's not easy behind the scenes.

Kardashian’s parents split up when she was about 10 years old — not much older than her daughter North is now

Kardashian got choked up as she explained how the importance of her relationship with her father

the late Robert Kardashian, motivates her to stay even keeled when it comes to discussing West at home.
