Scott Disick may still believe Kourtney Kardashian is "playing hard to get" when it comes to his attempts to rekindle their romance. But a new report from Page Six suggests Kourtney won't go back to her ex now for the same reasons she didn't marry him during the years they were together.

For starters, he's still partying. After checking in and out of rehab repeatedly over the past year, Scott, 32, went out drinking at Coachella with Kourtney's 18 and 20-year-old sisters, Kylie and Kendall Jenner, last weekend.

"Scott says he still wants to get back together with her, but hasn't done anything to prove it," a source tells the New York Post. "Kourtney is over it. She knows she looks amazing and she isn't putting up with any of his s---."

The insider says Kourtney's made it clear Scott "needs to show how much he's changed" before she'll even consider getting romantically involved with him again.

"But instead he's out partying at Coachella and will complain to his guy friends about how many rules Kourtney imposes on him," gripes the source.

Though the insider notes Scott now "sticks to beer and avoids shots so he doesn't get too wasted," it seems the mother of his three young children, Reign, 1, Penelope, 3, and Mason, 6, hoped Scott might set his own personal sobriety bar a teensy bit higher than "not too wasted" after all those trips to rehab.

Or maybe ignorance is bliss for Kourtney these days.

"She doesn't ask her sisters about Scott's behavior when he's out," the source says. "Her attitude is he can do whatever he wants, but she knows she ultimately has the upper hand and Scott keeps it respectful when he's around her sisters."

The other big issue for Kourtney is Scott's lack of career direction. At this point, the boozing and clubbing is built into his schedule, which doesn't exactly make him prime marriage material.

"She's made comments to her family about how his behavior [with money and partying] is exactly why she never married him," the source continues. "He doesn't really have a job beyond his club appearances and paid Instagram posts and hasn't given up drinking."

While Scott's returned to the path he was on before he and Kourtney broke up, Kourtney, who turned 37 on April 18, has reportedly refocused the priorities in her own life.

The insider pointed to a clear "difference in how she's changed since the split," noting Kourtney has been "working on building her own personal brand" with more determination than ever.

She's allowed Scott to remain part of their children's lives and has been open to how that impacts her own life, but she seems to have remained committed to her independence.

"By the way, everyone relax," she said in a recent Snapchat, dismissing the notion that she and Scott have a future as a couple. "We have three kids together. We spend time together."
