The 'Keeping Up With the Kardashians' star - who ended her relationship with her longterm partner in July over his wild partying ways - thinks her former boyfriend needs to make a lot of changes to "get on a good path".

During a scene on last night's (29.11.15) episode of 'Keeping Up With the Kardashians', her sister Kim Kardashian West told Kourtney: "I feel like he had fun and then when reality set in he was just like 'Oh s**t!' "

Kourtney - who has children Mason, five, Penelope, three, and Reign, 11 months, with Scott - replied: "Yeah but I feel like that's kind of what happens every time. Like he would be home and be really good for like three months and then go out of town and be like worse than he was before.

"He has like two personalities that's the hard thing. It's like he wants both, he's like 'I just want my family' or whatever. And I'm just like 'Well what are you doing to try to change your life?' "There's just like a lot that would have to happen for him to get on a good path."

However, their conversation was interrupted when Scott walked into the room, much to Kim's "shock" as he had "obviously" spent the night at the house.

Kourtney later explained why the 32-year-old star had stayed over, claiming he was unable to get a room in a rehab clinic until the following day and didn't want to be alone.

Later in the episode, Kourtney branded Scott a "real f***ing a**hole" for "flaking" on their kids too often.

Explained why she had withdrawn her open door policy, she said: "He was flaking too often, every time I tried to have him sit and have dinner with them he sits in the other room on his phone.

"He flaked on going to the kid's first day of school, he says 'I can't go because I hate school s**t, I get anxious.' When really he went out and partied through the next day, just like a real f***ing a**hole.

"His main concern is himself, not the kids and that's what's important here is the kids."
