IS KRIS JENNER STOPPING 'UNHAPPY' KIM KARDASHIAN DIVORCING KANYE WEST?
In a new episode of Kourtney And Khloe Take The Hamptons, Scott will be seen opening up about his issues.
He said: “It became like a 24-hour job to stay trying to get drunk, and stay trying to take pills and not think about life.”
But it’s obviously becoming a lot for Kourtney, 35, who is pregnant with their third child, as she asks for space to ‘think clearly’.

An unhappy Scott replies: “How much space do you need? We haven’t slept together in five years.
"What’s the difference?”
His outburst is a bit confusing to say the least, considering Kourtney’s expected to give birth any day now.
In an earlier episode of the reality show, Scott appeared to down a bottle of pills and required hospital treatment.
Scott later opened up to his partner about the incident, telling her that rehab may be his only option.
He said: “I need to make a change and that may be checking into some kind of facility.”
