Kourtney Kardashian is "at her wit's end" with Scott Disick.
The 'Kourtney & Khloé Take the Hamptons' star is reportedly getting fed up of her partner's constant partying, after rumours surfaced that the 31-year-old model was planning to make a number of club appearances in cities across the United Kingdom.
A source said: "Kourtney feels like an idiot for ever really believing that things would change. She is at her wit's end right now.
"Kourtney knows what Scott was up to while he was away. And Kourtney did not need to read the tabloids to know what he was up to."
The 35-year-old television personality's pals are reportedly urging the star to leave Scott, with whom she has Mason, 5, Penelope, 2 and six-weeks-old Reign.
The source continued: "She has gotten so much c**p from her friends and she doesn't even know what to say anymore. It is like a broken record and her friends have told her countless times to leave him. She would be better off.
"Scott is just such a charmer and a sweet talker that he can turn anything around."
The mother-of-three is also reportedly "really glad" that she hasn't tied the knot with her partner of more than eight years.
The insider told RadarOnline.com: "Scott is the only one who has this kind of power over Kourtney.
"She is just really glad that she did not ever end up marrying him, because this would be a lot messier than it already is."
