In a clip from Sunday’s new Keeping up with the Kardashians, Kim Kardashian West and Kris Jenner explain in detail how the family confronted Tristan Thompson about his cheating, just days after Khloè Kardashian game birth to baby True.

Unfortunately didn’t happen on camera, but big sister Kim in a one-on-one Kim confesses they didn’t film the meeting because they “really wanted it to be a private talk,” where they all “expressed exactly how we felt.”

“He was very remorseful and feeling obviously sick over everything that happened,” Momager Kris explained to cousin Cici Bussey, but Kim was quick to interject, “But I told him, ‘I think you’re more remorseful because it’s affecting your job. I think he’s more embarrassed that he looks stupid ’cause the public and booing him, and I think it’s more of that than anything and I told him that.”

One thing they all wanted to know according to Kris, was “how many more of these things are we supposed to prepare ourselves for?”  Speaking to the camera, Kim added, “I think the convo was going OK at the beginning and then it got heated, and I don’t know, it just kinda took a left turn.”

According to Kim, they heard him out because he is the father of Khloe’s child, something Kris said only made the situation all the more shocking for her daughter, “She said something really interesting, she said, ‘I didn’t have a baby just to have a baby and move on.’ She said ‘I had a baby to create a beautiful family’ and that’s what broke my heart. She really never saw it coming either.”
