"I had therapy with Tristan on Saturday. I desire to have a good coexisting relationship with him, but I can't see myself ever being able to trust him," Khloe told Kim on Sunday's new episode of "Keeping Up with the Kardashians." "He said, 'I know you and your family made this a big media thing.' I'm like, 'Would you think I would want this out there?!'"
"Not in a million years would you have wanted this public," Kim fired back. "That's what people perceive."
"At the end of the day, it's already out there," Khloe said. "If Tristan was gonna cheat, he was gonna cheat, it was gonna be public at some point. I'm so offended it had to be with her."
That's when Khloe revealed she had gotten a message from Kylie Jenner's former best friend saying she "wanted to talk," but Khloe had little-to-no interest.
"I don't know if I need to talk to her," she explained. "Like, I don't get closure out of this deal because I will never feel like I can let her back into my life again." Kim assured her she didn't have to.
"I feel like Kylie's leaning more towards that, and that's fine, and for the love of my sister, I don't mind talking to her," Khloe said. "I know what happened, so if Kylie wants her around, I'm not gonna be argumentative and fight back. I just have to move on."
In her confessional, Khloe added, "Kylie lost her best friend, and I feel like sometimes my situation overshadowed hers, and she's at a loss as well. So I kind of want to ask Kylie if she wants me to have that conversation."
Khloe decided the best time to bring up said topic was on a girls trip to Napa Valley to go wine tasting. Naturally, she and Kylie brought along Kris Jenner, because no event is ever less fun with that woman.
"You lost a lifelong friend. I feel really bad about that," Khloe began. "I just want you to be happy."
"I feel like this whole situation needed to happen for a reason. For me, for her, for you, for everybody," Kylie replied. "She was my security blanket. She lived with me. We did everything together. There's a part of me that needed to grow without her. Sometimes, people are there for certain reasons at certain times in your life, and not there for others. Obviously, I love her. Right now, she's kind of doing her own thing. I'm doing my own thing. So I'm kind of just going with the flow. I'm happy, for some weird reason."
Khloe praised her little sister for being so wise and confident, which touched Kylie. But she couldn't take all the credit. She said her supportive family was "a lot of the reason why I am the way I am." Khloe agreed, adding, "We'll always have each other."
