As for what led to their split in the first place, Kourtney says Scott's substance abuse struggles were "the deal breaker," not his infidelity, as she "only knew about it at the end."
Scott agrees, with both he and Kourtney stating that he would've had a chance with her if he had maintained his sobriety.
"I don't wanna make any excuses for my behavior," Scott says. "I definitely wouldn't have done these things sober, but it was all wrong. I just thought it was normal, to be honest... I was somewhat young and didn't really know the difference."
