Sofia Richie 'Wishes' Ex Scott Disick Had Kept Their Relationship Issues Private: Report

Scott Disick opened up to the Kardashians about the relationship issues he had with ex Sofia Richie prior to their split, and a report says the model is apparently not surprised by his move.

In the premiere episode of "Keeping Up With the Kardashians" Season 20, the Talentless founder shared that Richie had given him an ultimatum. She reportedly wanted the mother of his kids, Kourtney Kardashian, completely out of his life.

An unnamed E! News insider confirmed that Richie had been jealous of Kardashian when she was still dating Disick. She reportedly felt that she was losing Disick to his ex-partner.

"Sofia and Scott had to navigate many issues together throughout their relationship," the source told E! News. "It was no secret they had their ups and downs when it came to Kourtney. Once Kourtney and Scott became closer and were spending more time together with the kids, Sofia had a huge issue with it. She thought she was losing him to Kourtney and was jealous at times."

The 22-year-old model wasn't surprised that Disick went public with their private matters, according to the source. However, she reportedly hoped that he would keep their discussions between the two of them.

"Sofia is not surprised that Scott shared their relationship issues with the Kardashian family and publicly on the show. She wished it stayed private but knew it would happen when they split. Sofia has moved on and put the drama behind her. At this point, there is no chance they will ever get back together," the insider added.

On Thursday's episode of "KUWTK," Disick told Kim and Khloe Kardashian that Richie wanted him to choose between her and Kourtney. However, he said he couldn't give Kourtney up because she and their kids -- Mason, 10, Penelope, 8, and Reign, 5 -- are a "unit."

"She was like, 'I don't want to share you as a boyfriend with Kourtney. And then she literally said with an ultimatum: 'You have to choose me or Kourtney,'" Disick said.

In a confessional, Disick made it clear that he had no plans to cut ties with Kourtney.

"I'm never going to give up my relationship with Kourtney and the co-parenting we have, nothing in a million years, will be worth what we have," he said. "And I truthfully believe if the right person were to even come along into Kourtney's life, or my life, us having children and having this amazing relationship would only be a plus to the outsider."

Disick and Richie called it quits last year after nearly three years together.
