Though they’ve spent quality time as a family with their three children in recent months, don’t expect Kourtney Kardashian and Scott Disick to rekindle their romance.

“They are very, very unlikely to get back together,” a source tells PEOPLE of the former couple. “She would never say never, but he needs to completely change his personality.”

The couple – parents to Mason, 6 , Penelope, who turns 4 next month, and Reign, 18 months – broke up in July 2015. Disick checked into rehab to work on his sobriety in October.

“He needs structure, a job and a role to stop him from falling off the wagon,” adds the source.

In an April episode of Keeping up with the Kardashians, Kardashian, 37, downplayed the possibility of a reconcilation.

“When it comes to Scott, I’m not looking to get back together any time soon,” Kardashian said.

Ahead of Kardashian’s birthday in April, a source told PEOPLE the star was doing well in the months since the split.

“It took Kourtney months to get to where she is right now,” the source said, saying she’s “happier and confident lately.”

Added the source, “Kourtney and Scott are in a good place. They are getting along and very friendly.”
