Scott Disick has 'regrets' about the way he treated Kourtney Kardashian

Scott Disick 'regrets' the way he treated Kourtney Kardashian, a source has claimed.

The pair famously met at a party in 2006 and had an on and off relationship until 2015, when they decided to call it quits.

During that time, Kourtney had three kids with Scott - Mason, 12, Penelope, nine, and Reign, seven.

A source has now told ET that Scott apparently 'regrets' how he handled his relationship with Kourtney.

"Scott will always have regrets about how he treated Kourtney and handled their relationship," the source said.

"He is focusing on moving on, accepting his faults, and trying to learn from his mistakes.

"He wants to get married one day and start his next chapter, but he isn't trying to do that right now.

"The Kardashians still talk to him almost all the time and they see each other relatively frequently. It isn't a toxic situation for anyone in the family and they've moved past any difficulties.

"He's been doing his best to stay out of any trouble or drama and just be a great dad."

Tyla has reached out to Disick's representatives for comment.

Earlier this year, another source close to Scott told US Weekly that he has not yet been able to bring himself to watch the Kardashian's new series on Hulu.

"Of course it’s awkward for Scott," the source claimed.

"He doesn’t take the time to watch the full episodes and why should he? He doesn’t need to. That’s the last thing he wants to do – relive the awkward moments of him, Travis and Kourtney. He lived through it already.

"He showed up and gave the cameras what they wanted, and at the end of the day, he’s getting a nice pay check."

Last month, Kourtney expressed her rather bizarre wish to breastfeed sister Khloé's newborn son.

Khloé, 38, welcomed her second child with Tristan Thompson back in July via surrogacy, and is yet to officially name the baby - a clearly ongoing trend in the Kardashian family.

Kourtney, who has three kids, is now stepmother to her husband Travis Barker’s kids - 18-year-old son Landon, 16-year-old daughter Alabama, and Travis’ 23-year-old stepdaughter Atiana.

Despite having a lot of children to look after, the 43-year-old clearly still misses having a little one.

While holding Khloé's newborn, she said: "When they open their mouths and just the way they smell. I wish I could breastfeed you."

To which Khloé responded with: "Oh, my God, Kourt, let’s calm down."
