Scott Disick says being a "better person" is "not the simplest thing".
The 34-year-old reality television star - who has mason, seven, Penelope, five, and reign, two, with his former partner Kourntye Kardashian - has admitted he is struggling to "handle everything that well" because he doesn't have a strong "support team" around him, and as much as he tries to change for the better he finds it hard.
Speaking on Sunday's episode (12.11.17) of 'Keeping Up With the Kardashians', the entrepreneur - who has sparked up a romance with Sofia Richie - said: "Obviously I'm not able to handle everything that well," he said. "I don't have the best support team. I can try to f***ing be a better person, but it's not the simplest thing."
But the TV personality - who dated Kourtney for almost 10 years - has joked he still wants to marry the brunette beauty.
Speaking about his future with the mother of three, he quipped: "When do you think we're going to get married by the way, like 40?"
However, Kourtney has outright refused to rekindle their romance.
She replied: "You think when I turn 40 I'm going to go, hey I've been looking for this drunk guy and he has a bunch of dirty s**t stained underwear?"
Kourtney and Scott came to blows recently when he wasn't invited to Khloé Kardashian's surprise birthday party, and though Kourtney didn't want her previous lover at the bash she came up with an excuse in fear of hurting his feelings.
She said to Scott: "I didn't want you to coming to the birthday and be photographed going in.
"There's times when I want you to come and there's times that I don't."
Scott replied: "Photographed going in is your concern? My concern would be ... to be there for your sister who I love and cared about for the past 10-12 years and been there for through thick and thin and marriages and all these different things."
But Kourtney opened up about her true feelings to her 33-year-old sibling.
She said: "I'm a little bit caught off guard and I just said that I didn't want to be photographed even though that's really not what I meant. I just try to be positive. And I didn't want to say I just didn't want you there. So if I can't say anything nice, I just won't say anything at all."
