Kourtney Kardashian has given Scott Disick six months to prove himself.
Scott Disick and Kourtney Kardashian
The couple - who have children Mason, six, Penelope, three, and Mason, 16 months, together - split last July after nine years of dating and though the 32-year-old model has got sober and vowed to change his party lifestyle, his former partner wants to see proof he has made a long-lasting change before she'll reconsider their future together.
A source said "This good behaviour could all be over in a few weeks so she's saying the only option is to make him prove how much he has changed, then she'll make a decision in six months time.
"She loves Scott but it's a big gamble taking him back."
While Kourtney is uncertain about what to do, Scott is keen for them to forge a happy family life together away from the 'Keeping Up With the Kardashians' cameras.
The source told heat magazine: "Half of her has fallen for him hard again but the mother in her wants to protect herself and kids.
"He's talking marriage and another baby - this very committed future, with them quitting the show and him finally getting his own businesses up and running.
"He's saying all the right things, but Kourt can't trust him yet."
