Few couples can fit so much needless drama into such little time as Kourtney Kardashian and Scott Disick.
It's actually kind of impressive when you think about it.
Kourtney and Scott have been making their relationship turmoil stretch for years and years now -- Scott will go on a booze-fueled bender or a dozen, Kourtney will make ultimatums, the cameras will catch it all for Keeping Up with the Kardashians.
Wash, rinse, repeat. Forever.
Of course, back in 2015 Scott crossed a line when he was photographed cozying up to a woman that wasn't Kourtney, and he promptly got dumped. For real dumped, not just dumped for reality TV.
He spent a few months being perhaps in the worse shape he's ever been in, but he managed to pull his life together, and it seemed for a while there that he and Kourtney were actually going to make it.
But old habits die hard. So, so hard.
Last month, Scott accompanied Kourtney on a family vacation to Costa Rica. They had some quality family time, but it didn't last because Scott reportedly had brought some girl along with him and was hiding her from Kourtney and Ko.
After a nasty little fight, Scott left the vacation early to jet off to Miami, where he was spotted with numerous girls in numerous compromising positions.
And when he finally made his way back to L.A., he didn't receive the warmest of welcomes.
According to an insider, "Kourtney told Scott that she doesn't want anything to do with him right now. She wouldn't even let him in their house."
So yeah, it's safe to say that things aren't going so well between them.
Things are so bad, in fact, that a source tells Radar that Kourtney is caught in a downward spiral of her own.
"Kourtney has been really down since Scott and her split again and she is starting to isolate," the source says.
"Kourtney is trying to pretend she doesn't care but she does. Scott will always be the love of her life."
Things are so bad that "Her friends think that Kourtney is in self-destruct move because she is drinking a lot and has started shutting everyone out."
"When Scott goes off on a bender, Kourtney is stuck playing the role of both parents and it is just really starting to take a toll on her."
And it gets even worse: on Wednesday night, Kourtney was photographed leaving church with none other than Justin Bieber, her old rebound.
Ideally Scott will realize the mistakes he's making and get back on a good path, but at the very least, we hope Kourtney can come to terms with his issues and avoid following in his footsteps.
