The former couple - who have Mason, five, Penelope, three and seven-month-old Reign together - split up earlier this month after he was photographed flirting with his ex-girlfriend Chloe Bartoli and although the reality star is devastated about the breakdown of their nine-year relationship, she is reportedly feeling more furious than upset.
A source revealed: ''Kourtney is devastated, but more angry than hurt.
''She is seriously turned off just by the thought of him.''
Fans of 'Keeping Up with the Kardashians' know the pair have had a turbulent past when it comes to their relationship, although recent events have been the final straw for the 36-year-old beauty, who feels ''sick to her stomach'' when she considers the possibility of reconciling with the 32-year-old hunk.
A source told PEOPLE magazine: ''Kourtney is so upset with Scott right now that the thought of taking him back makes her sick to her stomach.
''He crossed the line for the last time, and there's no turning back.''
Meanwhile, rapper Kanye West has stepped in to help his sister-in-law after Scott left and has been encouraging him to seek help in order for him to repair the damage he's caused.
A separate source said: ''Kanye told him he needs to man up and go to rehab.
''Kanye is furious, maybe the most furious of everyone. He's saying that a real man doesn't abandon his family like Scott is doing.''
