The reality beauty insists there would be "so much work" involved if she was to try to reignite her relationship with the 33-year-old star - who she has kids Mason, six, Penelope, four, and 20-month-old Reign with - despite the two of them being on good terms and "co-parenting" for their three children.
In fact, in a teaser for this Sunday's all new episode of Keeping Up with the Kardashians, Kourt is konflicted about attending Scott's 33rd birthday bash in Sin City from back in May!
Kourtney then explains, "I'm just not sure if I wanna go".
"Right now I can't even wrap my head around that idea", she says about reuniting with Disick. "I don't know [if I miss him]".
It's his party... and she'll go if she wants to.
"Would Kourtney be open to getting back together?"
As a result, Kourtney vented her anger to Rob, who was less than pleased with how "unsupportive" he felt his sister was being. He was like, 'I'm going to go on the red carpet tonight and I'm going to tell everybody how I have the worst, most unsupportive, disgusting family!'
"At my core, I don't believe in divorce, but I came to a point in my marriage where I had to make the choice to take care of my own mental and emotional well-being in order to protect myself and my happiness".
