Kourtney, 36, allegedly called time on her nine-year relationship with 32-year-old Scott after he was spotted partying with rumoured ex-girlfriend Chloe Bartoli.
Scott has allegedly avoided returning to their home until now – but now has had to face the music.
A source told HollywoodLife.com: “His first face-to-face with Kourtney was not good at all.
“Kourtney is over the crying and just feels anger when it comes to Scott. She’s mad at him for not pulling his sh*t together.”
Although reality TV star Kourtney was less than pleased to see her estranged partner, their children, Mason, five, Penelope, three, and seven-month-old Reign Aston, were allegedly over the moon that their father had returned home.
The insider continued: “He went straight for the kids, giving them all huge hugs and kissed. They were so happy to have him back. He played with them for a little while before reading them bedtime stories and [then] putting them to bed.”
But his reception from Kourtney was, understandably, frosty. “He was almost out the door when [she] started to give him a hard time, making passive-aggressive comments about his behaviour,” the source added.
“He started bawling his eyes out. He told her he doesn’t feel great about what happened, or how he’s acting, but [he] said they both played a part in the destruction of their relationship.”
The famous couple are now said to be focusing solely on their children and a reunion is out of the question.
