'She's Losing Control:' Family Fears Kourtney Headed For Breakdown After Younes Split

She’s always been the sensible one, but after her shocking split from boy-toy Younes Bendjima, RadarOnline.com has exclusively learned her reality TV family fears Kourtney Kardashian is headed for the mother of all breakdowns.

“She’s hurting and humiliated after her split from Younes,” a source told RadarOnline.com. “She always thought she knew what she was doing, even with the huge age difference between them.”

As RadarOnline.com revealed, Kourtney cut ties with the 25-year-old in early August because she had been unhappy with their relationship for a long time.

But seeing Bendjima almost instantly rebound into the arms, and lips, of former Las Vegas waitress Jordan Ozuna, Kourtney lost kontrol.

“She’s gone completely into her shell, won’t talk to any of her sisters, and refuses any kind of therapy,” the source confessed.

Kourtney, 39, and Bendjima started dating in 2016 after meeting at a bar in Paris, months after the KUWTK star broke things off with baby daddy Scott Disick. Friends always considered him nothing more than a rebound, but it seems Kourtney has been left shattered.

“Kourtney scoffs that she’s fine, but she’s never turned her back on her family like she is now,” the source said. “They hardly see her, and when they do have to hang out contractually to film their TV show.”

Friends have admitted that Kourtney never really trusted her much younger man, and became suspicious in April when he spotted out with a mystery girl. That led to her hiring a private investigator to snoop on Bendjima.

Now, with the truth out there, Kourtney, who “feels like an idiot” for wasting two years of her life on him, is taking her frustration out on herself, and others.

“She’s silent and snaps at everyone,” the insider added. “No one knows what she gets up to when she’s alone and Scott has the kids, but all signs are pointing to it not being good.”
