Kourtney and Travis had been longtime friends and neighbors before they started dating in January. While the couple's family members seem thrilled over their engagement, a source tells ET that Scott Disick, Kourtney's ex and the father of her three children, is still processing the news.
"Scott is stewing over Kourtney and Travis' engagement and not happy at all," the source told ET earlier this week. "He's lonely right now and not in a relationship, and is very jealous that things are working out for Kourtney. Scott would prefer to go back to when him and Kourtney were just getting along as co-parents without anyone else in their lives romantically."
The source added, "He's trying to figure out his next move when it comes to their kids. Kourtney is trying to ignore any negativity from Scott because she has been down that road too many times to count and is just enjoying this moment."
