Kourtney Kardashian ''hasn't made a final decision'' about Scott Disick.

The 36-year-old star has not ruled out getting back together with Scott, 32, after they separated earlier this month and is instead ''just living day to day'' while she works out what she wants.

A source revealed: ''Scott is not totally out of the picture.

''She hasn't made a final decision. Right now, she's just living day to day. She's not begging him to see the kids, but she also hasn't definitively said 'I'm never letting him back again.'''

The 'Keeping Up with the Kardashians' stars - who have kids Mason, five, Penelope, three, and seven-month-old Reign together from their nine-year relationship - reportedly split because Kourtney was sick of his constant partying, but she is now re-evaluating her life to see what it would be like without him in the picture.

The source told People magazine: ''For the first time, she's taking a hard look at what her new reality could look like.

''Before, she just assumed nothing would really change, but now there's a strong possibility of life without him, and that's a scary thought for her. She was doing most of the work already, but at the end of the day, she would still turn into a single mom of three kids.''
