Scott Disick Opens Up to Kourtney Kardashian About Split from Sofia Richie in KUWTK Sneak Peek
"I think people come into our lives and think it's maybe easier than they think," he says in the preview. "But it's very true that we come with a lot of baggage. It's definitely not easy that we see each other, work together and are friends."
Disick admits to Kardashian 41, that he doesn't think he could handle the pressure if the tables were turned, before adding that he has priorities he needs to focus on.
"I've always been clear that my priority has been my children, my life with them ... I even put it out there that taking care of you is one of my priorities," he tells Kardashian.
Disick tells the cameras that Richie — whom he officially split from in August after nearly three years of dating — was "an absolute trooper," but "anybody dating somebody is going to feel neglected when their significant other is spending more time with their ex than with them."
In the final moments of the clip, Kardashian tells Disick that she loves that their kids benefit from the two of them having a strong relationship, but she doesn't want him to be afraid to make his significant other a priority too.
"I do think we have to be respectful of our relationship and make sacrifices for that if it means a lot to you," she says.
