Those are pretty normal things for Kourtney to feel at the end of the year that saw her split from Scott Disick, her boyfriend of nine years and the father of her three children. The couple's split became public in July, after Disick was spotted vacationing with an ex-girlfriend. Their youngest son, Reign, was barely 7 months old at the time.Since then, they've had some ups and downs as co-parents. In October, Disick entered rehab for alcohol and drug abuse. In a November episode of Keeping Up with the Kardashians, Jenner and Kardashian confronted Disick about flaking out on the kids during visits. But by Thanksgiving , things were going well enough for him to attend the family's celebration. It's not clear whether he was at the Christmas party this year.
