Subscribe now to get the exclusive inside scoop on how Scott ‘threw it all away’ and why Kourtney finally ended it, only in PEOPLE! Scott Disick still believes there is a chance that he and longtime girlfriend Kourtney Kardashian will reconcile following their split earlier this week, a source close to the star tells PEOPLE. “Scott says that he’s doing fine,” the source says. “He says that he is not upset that the relationship is over, because ‘over’ doesn’t always mean ‘over.’ He has left open the door to getting back with her.” Disick and Kardashian, with whom he shares three children (Mason, 5, Penelope, 3, and Reign, 6 months), broke up after nine years when Disick was photographed cozying up to Chloe Bartoli, a 25-year-old stylist. His long struggle with substance abuse was also partially to blame for the headline-making split. The source says that Disick, 32, isn’t seeing the break up “clearly” and thinks an apology will fix the rift between the former couple. “But he’s open to the idea that she may not forgive him and it may really be over for good, and he’s okay with that, too,” the source tells PEOPLE. “Right now his feeling is, whatever happens, happens.” RELATED VIDEO: Scott Disick Says His Daughter Is One of the Few Things He’s Proud of in Life The insider, who fears the breakup eliminates any incentive Disick had to get a handle on his drinking, says that the reality star is aware he didn’t handle the situation in “the most healthy of ways.” “When he decided that he wasn’t willing to keep the relationship going, he needed to man up and face Kourtney like a man. He didn’t do that,” the source says. “He found the most painful way to act out. That’s what he was doing: acting out.” The Keeping Up with the Kardashians star was actively checking social media to see coverage of the split but “didn’t care” about the negative reaction, the source says. Perhaps proof of Disick’s nonchalant attitude, his first two posts on social media following the scandal were an invitation to come “party in Vegas” on Friday and a shot of a vintage car he’s currently coveting. Although Disick wasn’t a part of his daughter’s birthday celebratoin at Disneyland, he eventually wrote on Instagram Wednesday night that Penelope is “1 of the only things I’m proud off about myself.” https://instagram.com/p/45I4ssO32o/ “Humility isn’t Scott’s strong suit, but if he wants to move forward in any sort of healthy way, he needs to be humble and apologize,” the source says, noting that any chance of Scott’s reconciliation with his ex and the family who’ve stood up for her depends on whether Kardashian is willing to forgive.
