Scott Disick has "mixed feelings" about Kourtney Kardashian's marriage to Travis Barker but The Kardashians star won't let him "ruin her moment." Scott hasn't publicly congratulated his ex on tying the knot and has continued to distance himself from Kourtney while maintaining their co-parenting arrangements. The Talentless founder hasn't been one ounce supportive of Kourtney and Travis's relationship. But the Poosh founder isn't letting her ex burst her love bubble and is instead focusing on her new life as Mrs. Barker.

Kourtney and Travis have continued to tour Italy after exchanging their vows in an intimate castle-side ceremony on Sunday. The Barker kids remained in Italy with their dad and stepmom while the three Disick kids returned to Los Angeles to be with their dad. Scott's resentment towards Kravis has reportedly put the Disick kids in the middle because of their loyalty to their dad. Scott opened up while filming the new Hulu show and admitted to feeling insecure about feeling left out now that Travis is in the picture. Scott also now realizes what he lost out on with Kourtney seeing her so happy with someone else.

But Kourtney is remaining unphased by Scott's "mixed feelings" about her marriage due to how "excited" she is "to be married to Travis," sources tell ET. "She knows she went through so much with Scott for years and she’s emotionally done," the insider explained. After years of "crying" over Scott and being "worried about him", Kourtney is finally focusing on herself, the source shared. With Scott being the father of her three children, Kourtney is aware of the lifelong relationship she will have with him. But she won't let him impact her married life with Travis. Kourtney "feels like she is a better mom and person now with Travis," the source said. "She isn’t going to let Scott's feelings ruin her moment."

Travis, Scott, and Kourtney

It took Kourtney falling in love with Travis for Scott to finally realize what he had during their nine years together. Despite being broken up since 2015, Scott still "loves Kourtney, but he also knows she is very happy," the source said. Seeing Kourtney so happy with Travis has made Scott realize his "regrets about how he treated Kourtney during their relationship," the insider shared. With the Disick kids being old enough to notice the tension between their parents, Mason, 12, Penelope, 9, and Reign, 7, have been put in the middle. All the while, Scott is still single and ready to mingle. Fans have noticed him leaving flirty comments on model's Instagram pages and he enjoyed a night at the strip club in New York on Kourtney's wedding day.

After dealing with Scott's self-loathing antics for over a decade, Kourtney is relishing in her newfound happiness as a married woman. Insiders say she loves signing her new married name and being reminded that she's Travis's wife. It took The Kardashians star over 40 years to finally walk down the aisle and she's not going to let an ex from her past affect her future with her husband. The KarJenners have continued to support Scott and show him that he's still part of the family. That should hold him over as he continues to adjust to Kourtney finally leaving him behind.
