Disick revealed this during the reality show 'Keeping Up With The Kardashian' which is on its final season

"I thought I would give it a try and make her more of a priority, but then even when doing that, I feel like she just started wanting to push Kourtney out...And I said like, that's the most important thing to me is my kids and that's my family, and the only family I have, including you guys along with it."

"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 went on to say that their relationship became impossible to keep carrying on with.
