Several years and three kids into their relationship, Disick is reportedly hoping his longtime love, Kardashian, will allow others to have sexual relations with her man. Although Disick claims the idea would likely work to their benefit, Kardashian is reportedly heartbroken over the request.

“He’s broken her heart by requesting an open relationship, which he claims is increasingly common and will only strengthen them,” an insider told Radar Online on Friday.

Disick and Kardashian's relationship has long been seen on Keeping Up With The Kardashians, as well as its many spinoffs, and while they have gone through many ups and downs, they have remained surprisingly solid, and welcomed three children in the last six years.

Unfortunately for Disick, Kardashian doesn't seem to be on board with his idea for an open relationship.

“Kourtney is disgusted, of course,” the insider revealed. “She was hoping he’d check into rehab, finally set a wedding date and was even hoping to have one more baby.”

Instead, however, Disick has reportedly began drinking heavily, and now, "they’re back to square one."
