In a clip from an upcoming episode of “Keeping Up With The Kardashians,” Jenner sits down with her former stepdaughter, Khloe Kardashian to hash out what’s gone wrong in their relationship.

“I just really feel like over the last year and a half we certainly have grown apart,” Jenner says to Kardashian.

She continues, “Day after day after month after month, nobody calls, nobody checks in. Just, ‘Hey, how are you doing?’ I haven’t gotten that phone call from anybody. You can’t help but sit there and think, ‘OK, is it because I transitioned? They don’t like me anymore?’ I want to know what I did wrong, what I didn’t do wrong, what I did right, and move forward.”

Kardashian, who was defensive of her mother, Kris Jenner during the early stage of Jenner’s transition, explains that the Vanity Fair article — in which Jenner said some not-so-kind things about Kris Jenner — really upset her. But losing a “second father” hurt the most.

“For me, you’re all I remember, Bruce was,” Kardashian said. “So not having you in my life, it’s a huge blow because I’m like OK, my second dad, this guy that I’ve grown up with, that raised me, was taken away from me, but no one really let me have that.”

“Keeping Up With The Kardashians” airs Sundays at 9 p.m. ET on E!
