Kourtney Kardashian has reportedly ended things with longtime boyfriend Scott Disick, but he's going to fight for partial custody of their children and all the money he can get.

The Keeping Up with the Kardashians star, 35, finally had enough of Disick's booze binges, shopping sprees and failed rehab stints -- with the last straw being his alleged addiction to cocaine he kept a secret from her, Life & Style reported in its April 6 issue.

"She's given him more chances than anyone ever should," an insider told Life & Style.

Kardashian never married Disick because she had a feeling he'd never get his act together, according to the magazine, and their divorce would be one brutal process she'd never want to endure.

However, "even though they're not married, this could be one of the messiest and most expensive splits ever," noted the insider.

The couple is reportedly worth $50 million -- with Disick, 31, having contributed $6 million. 

Disick has recently blown through $5.5 million of their shared money on cars, nights out clubbing, shoes, watches and suits. As a result, Kardashian finally cut Disick off. It also apparently wasn't an oversight he was left of the Kardashians' new $80 million E! contract.

"He never uses his own cash," said the insider. "Even when he buys his kids expensive things, he charges it on credit cards that Kourtney pays for."

Even when Disick checked into the Rhythmia Life Advancement Center in Costa Rica for rehab earlier this month, the facility reportedly agreed to pay him to be their spokesperson.

Despite having a really tough few days of withdrawal, "people are worried nothing will work to sober him up because he has too much of an attitude," a source told Life & Style. "He thinks he's above everyone else. He won't last the 10 days he's supposed to be there. He's even dismissively filming his time in rehab on a hand-held flip-cam."

Kardashian and Disick had a final fight after the weekend of March 14 when Disick allegedly partied for two days straight in New Jersey and Chicago. He barely apologized to Kardashian when confronted.

"They had it out for the last time," the source explained. "That 48-hour period made her realize he is so out of control she can't trust him with money or anything else anymore."

And he "loves his cocaine," added the source. "When he is high, he twitches, but he still doesn't believe he has a problem. He's only in rehab for the six figures it's banking him."

The couple has three kids together: Mason, 5, Penelope, 2, and Reign, four months. Disick may reportedly use them as bargaining chips to get more money from Kardashian if they do split for good.

"He will fight for joint custody of the kids, which basically means he wants to continue getting paid," said the insider. "Scott's no dummy... [He] will hire the top lawyers in LA to take as much of Kourtney's wealth as he possibly can."

Disick will look for something along the lines of spousal support.

"Losing partial custody of her children is terrifying for Kourtney. But if she also has to continue paying for Scott and his antics, too, it would be the end of her world," a family source told the magazine. "Scott wants to be set for life."
