"I just really feel like over the last year and a half we certainly have grown apart," Jenner, 67, says.
"Day after day after month after month, nobody calls, nobody checks in. Just, 'Hey, how are you doing?' I haven't had 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," she continues.
Kardashian, 32, responds by pointing out that she doesn't want to say that the Olympic champion did anything wrong, "just because you didn't do something the way maybe I would have preferred that makes it wrong.
"This family we deal with things very quickly. We don't have time to really process a lot of things because we're always on to the next and for me at the time I just wasn't at a place in my life where I really could invest in new relationships or even something that's this heavy."
Khloé refers to Caitlyn's comments about Kris Jenner in her 2015 Vanity Fair interview.
"It was very hard for me to experience a lot of new things so quickly and still feeling like I have to protect my mom and certain things that were happening where I felt like they might not have been the most positive," she said. "But then I was also like, this isn't even my fight to fight anymore. I have my own s**t to deal with, so why don't you guys figure that stuff out. But I don't think Caitlyn is a bad person at all."
Caitlyn responds by pointing out that she was there for 23 years of her life. "Being there when you have good days and bad days and all the things you go through when you're growing up and sneaking out of the house and I found you and stuff like that."
"For me, you're all I remember. Bruce was," Khloé admits, "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."
