The Kardashians have distanced themselves from Caitlyn Jenner since her transition and now she's calling them out.

Jenner has a sit-down with former stepdaughter Khloe Kardashian in a sneak peek at Sunday's "Keeping Up with the Kardashians," during which the two talk about why there has been so much fallout between them since Cait came out in 2015.

"We haven't talked in a while. I just really feel like over the last year and a half we certainly have grown apart," Jenner says in the clip as the two sip on red wine. "Day after day, month after month, nobody calls, nobody checks in, just 'Hey, how are you doing?' You can't help but sit there and think, 'OK, is this because I transitioned? They don't like me anymore?'"

Khloe has been very open in the past about having a hard time with the transition and reveals her mixed feelings about the entire situation.

"I don't necessarily want to say you did anything wrong, I don't know if just because you didn't do something maybe the way I would have preferred, that makes it wrong," she says. "In this family, we deal with things very quickly. We don't have time to really process things because we're onto the next. For me, at the time, I wasn't in a place in my life where I really could invest in new relationships."

In case you forgot, Khloe was in the middle of her split from Lamar Odom and dealing with his hospitalization that same year.

"It was very hard for me to experience a lot of new things so quickly and still feel 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 continues. "I don't think Caitlyn is a bad person at all."

"For me, you're all I remember, Bruce was," she adds. "So not having you in my life, it's a huge blow. My second dad, this guy I've grown up with that raised me was taken away from me, but no one let me have that."

In another clip, Khloe and Kim Kardashian grill Scott Disick over his feelings about Kourtney.

When asked if he's over her, he says he'll "never be over her, she's the love of my life" -- before admitting "there's no appreciation for anything, ever" from her in return.

"A lot of things truly are my fault, I'm happy taking ownership for all of that," he adds. "I just hope that one day she understands that I would never want to be with anybody but her."

"Keeping Up with the Kardashians" airs Sunday on E!
