Seeing an ex move on is never easy! Just because Kourtney Kardashian and Scott Disick called it quits back in 2015, doesn’t mean that the KUWTK star, 40, is ready to see her baby daddy, 35, marry girlfriend Sofia Richie. “Kourtney is still on the fence about Scott marrying Sofia,” a source exclusively tells Life & Style.

“They have a lot of history, good times and bad, and even though Kourtney really likes Sofia, the thought of Scott being married to someone else, well, the feelings are bittersweet,” adds the insider. Unfortunately for Kourtney, however, she may be forced to get over those feelings sooner rather than later.

Scott and his 20-year-old ladylove have “talked seriously about getting engaged,” according to Us Weekly. “It’s a real possibility,” an insider told the publication. “As it is now, Sofia and Scott look at each other as life partners,” and “are in a great place and stronger than ever,” they noted. Hmmm, it’s no wonder then that Kourtney’s mom, Kris Jenner, is worried that Kourtney will one day be hurt by Scott and Sofia’s courtship.

“My fear is that she can’t make up her mind. She can’t pick a paint color, that takes months. I’m just saying, because of her indecisiveness, it’s going to bite her in the ass. She’s going to be the one deciding way too late that she is in love with Scott and wants to spend the rest of her life with Scott,” Kris confessed during a recent clip of the family’s hit reality show.

As much as we ship Scott and Kourtney, we’d hate for Sofia to be left in the dust. Sigh. Will this love triangle ever come to an end?
