Disick’s on-and-off relationship with Kardashian, 43, ended in 2015 after nine years. Currently, they co-parent their three children:Mason, 12,Penelope, 9, andReign, 7.

In the years since their split, Disick has repeatedly tried to win Kardashian back. Disick said onKeeping Up with the Kardashianslast year that he’d “marry” Kardashian “right here, right now,” but she said he still had to “work on” himself before they revisit the idea.

The former couple eventually chose tonot rekindle their romance. She then wound up falling in love with Barker, who is one of her longtime friends.

After their October 2021engagement, a source said that Barker — who shares sonLandon, 18, daughterAlabama, 16, and stepdaughterAtiana, 23, with ex-wifeShanna Moakler—treats Kardashian “like a princess and is a great guy.”

“Kourtney feels this is such a special relationship,” the source added. “She feels appreciated.”

Disickbegan “distancing himself from the family"after the engagement, an insider previously said.

“It’s not about them, it’s not about Kourtney. It’s about him needing some time to process this and deal with it on his own, without them,” the insider concluded. “He’ll come around soon.”
