Scott Disick Focused On Moving On Despite Regrets For The Way He Treated Ex Kourtney Kardashian: Report

Scott Disick has chosen to improve himself after his ex Kourtney Kardashian found her happy-ever-after with Travis Barker.

Disick had a hard time accepting Kourtney's relationship with Barker when it became serious. Now that his ex and the mother of his three children is married to the Blink-182 drummer, he is reportedly trying to move on and improve himself while regretting how he handled their relationship.

"Scott will always have regrets about how he treated Kourtney and handled their relationship. He is focusing on moving on, accepting his faults, and trying to learn from his mistakes," a source told Entertainment Tonight.

Disick and Kourtney share three children, Mason, 12, Penelope, 10, and Reign, 7. Just like his ex-girlfriend and baby mama, Disick is reportedly hoping to experience married life, but it's not his top priority at present. He is reportedly more focused on himself.

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

An anonymous tipster also spoke with Us Weekly and claimed that he was committed to "bettering himself" after several rehab stints in the past. Disick "has stepped up his treatment and therapy" and is focusing on improving "his mental well-being," the tipster said. The Talentless founder is also considering an in-patient program for his substance abuse struggles.

"The Kardashians are all very supportive of Scott bettering himself," the insider said. "They love him and want him to love himself just as much."

Disick and Kourtney dated on and off from 2006 to 2015. An insider previously told the outlet that his "breakup and past issues with Kourtney and his parents' deaths have deeply affected him."

Kourtney tied the knot with Barker in May. According to sources, Disick struggled to accept that she was already married.

"His feelings for her haven't gone away — he's always going to love her — he's just having a hard time accepting the fact that she's married," an insider told Us Weekly.

In an episode of Hulu's "The Kardashians," Scott confessed to Kourtney's sister Khloe Kardashian that his ex and Barker's relationship put a strain on his bond with the Kardashians. He admitted that he felt left out and lonely because after his parents' passing, his only family was them.

"Feeling left out and not being told anything is super hurtful — especially when I don't have another family to go to. I [will] rather be around them and be around my family than not at all," he said.
