We bet she's glad he's not really her problem anymore!

Kourtney Kardashian was all smiles as she stepped out for coffee with pal Larsa Pippen yesterday in West Hollywood, and the reality star clearly isn't bothered that ex-boyfriend Scott Disick is busy hanging out with her family in the Big Apple for NYFW.

The hard partying father-of-three was hospitalized in mid-August and placed on a psych hold, and although Kourt visited him, she's not stressing about what happens next because she's done trying to fix him. The eldest K sister has tried everything to get LD sober and living more responsibly, but nothing has worked. Now, she's happily dating boy toy Younes Bendjima and leaving it up to The Lord's friends to handle his downward spiral.

Scott's boozing sounds like it's stemming from his disbelief that his relationship with his baby mama is over for good.

"Scott really isn’t happy about Kourtney dating Younes. He hates the fact that Younes is younger, and hotter, and it drives Scott crazy jealous that Kourtney is clearly really into him. Scott has always assumed that Kourtney would be there waiting for him, no matter what—that he could go off and party, hook up with other chicks, and disappear for weeks on end, and that Kourtney would just take him back. It’s been a really serious shock to Scott’s system to realize that’s not the case, and that Kourtney’s moved on. Seeing photos of Kourtney and Younes frolicking together on holiday, and seeing how happy Kourtney looks, cuts Scott like a knife. But, let’s face it, Scott had his chance, many many times, and each and every time he blew it, so he has no one to blame but himself," a source dished to Hollywood Life.

"After years of putting up with Scott’s antics and outrageous behavior, Kourtney finally got to the point where enough is enough. She’s truly done with being taken for granted and treated like a doormat. She’s really happy with Younes, she’s happier than she has been in years in fact—Younes treats Kourtney so well, and makes her feel really good about herself once again. Scott can sulk and bitch all he wants, Kourtney’s done with him once and for all, and he has no-one to blame for that than himself," the source added.

Sometimes letting go is the best decision you ever make!
