Kourtney Kardashian may be ready to give Scott Disick another chance.

Kourtney and Scott are currently "trying to make it work" following the 32-year-old reality star's month-long stint in rehab, a source close to Scott tells ET. But the 36-year-old Keeping Up With the Kardashians star isn't quite ready to take back her ex just yet.

"Kourtney hasn't let Scott back in with open arms," the source says. "They're not 'not together,' but they're not 'together' -- they're not seeing other people, but at the same time she's not ready to take him right back. She's still making sure he's OK. He's still making sure he's OK. It's going to be a long road but he's doing well."

"He feels good and healthy," the source adds. "He's doing the best he's been in a really long time."

Kourtney and Scott are clearly at least currently on good terms. The two spent Thanksgiving weekend together as a family, attending the holiday dinner at Khloe's house and then cuddling up on a Black Friday luxury furniture shopping trip. Each also shared pictures of them hanging out with their three children -- Mason, 5, Penelope, 3 and Reign, 11 months -- on Saturday night, in what appears to be the same home.

However, our source the two are still not living together. "Scott is not living at home with Kourtney right now," we're told. "He does still have his rental house. Scott is at Kourtney's house a lot."

According to the source, Scott is truly looking to change his partying ways, and has even given up many appearances and offers since going into rehab in order to "resist temptations and bad influences around him."

"This is the first time he's being smart about it and everyone is hoping it lasts," the source says. "Scott is trying to lose his party boy image. He's doing that for himself, too."

Scott's upcoming hosting gig at 1OAK's New Year’s Eve bash in Las Vegas will reportedly be a "big test for him," our source says.

One Kardashian who we know for sure is rooting for Scott is 60-year-old Kris Jenner. Aside from visiting Scott in rehab in October and having dinner with him last month, Kris also called the controversial reality star one of the "true loves of [her] life" in a sentimental Instagram post on Tuesday.

"This is one of the true loves of my life... Feel so blessed to have him as the baby daddy to my Grandkids," she gushed. "You are amazing @letthelordbewithyou and I love you. #proudmama #memories #family #youareeverything."

Last Wednesday, a beaming Kourtney sparked reconciliation rumors with Scott when the two were snapped having lunch together at Marmalade Cafe in Calabasas, California. Kourtney was "laughing and smiling" and seemed "happy and a little shy," while Scott appeared "confident and comfortable" and "was a gentleman towards Kourtney," an eyewitness told ET about the outing.
