The 36-year-old reality star ended her relationship with the 32-year-old model back in July and in a forthcoming episode of 'Keeping Up With The Kardashians', viewers will witness the mother of three's heartache.
In a clip of the E! series, Kourtney is seen confiding in her sister Kim as she wipes away tears. She says: "I've worked so hard to keep this family together."
Two months agos photos emerged of Scott cosying up to his ex-girlfriend Chloe Bartoli in Monaco which prompted Kourtney to cut ties with the father of her children, Mason, five, Penelope, three, and nine-month-old Reign, after nine years together.
In the episode, Kris Jenner can be seen sitting at the table with a tearful Courtney and Kim and she gets angry when reading the story of Scott's romance online. She says: "What a piece of s**t!"
Despite Scott, 32, missing his family, he is not prepared to change his partying ways. A source said: "Scott misses his family, but it's not enough to motivate him to change. He doesn't have the constitution to cure himself of his issues."
