Kourtney Kardashian is reportedly regretting her decision to dump longtime boyfriend Scott Disick. The mother of three is said to be open to letting her ex back into her life, but only if he sobers up.

According to Us Weekly, a source close to the petite beauty stated that she is now regretting her rash actions following Disick’s European trip. Kardashian broke up with her children’s father shortly after photos of him surfaced from a trip to Monaco in the first week of July. He was seen getting close to his ex-girlfriend Chloe Bartoli on a beach.

“She wants Scott back,” said the source. "She hopes this will scare him enough to get help. If he gets to the point where he is really changing, she'll let him come home.”

Disick has long had troubles with alcohol and substance abuse. The former couple have fought about the problem on numerous occasions. Many of their fights have been documented on episodes of “Keeping Up With the Kardashians” and its various spinoffs over the years.

Kardashian is reportedly hoping that this breakup will scare Disick into getting his act together. There are conflicting reports about her plans about seeking joint or sole custody of their children. The Us Weekly source said that she wants sole custody to scare Disick. Other reports, however, have previously stated that she wants joint custody to allow her children to have a healthy relationship with their father.

Regardless of any custody battle, Disick has been spending a lot of time with his children despite the breakup. In the past two weeks, he has been spotted with them on numerous occasions. Last week, he even had lunch with Kardashian and their two oldest children. The former couple have 5-year-old Mason, 3-year-old Penelope and 7-month-old Reign.

This isn’t the first time that the couple has broken up. In fact, they were not together when Disick reportedly went out with Bartoli back in 2006. Disick had also been kicked out or not allowed back into the house on numerous occasions after partying. The pair always got back together quickly, but this time, things are different. The source said Kardashian is “shocked” that Disick isn’t begging her to take him back as he would do before.
