The Kardashian family is deeply divided over Kourtney's decision to stay with Scott Disick, reports the new issue of Us Weekly, on stands today.
"Kourtney feels like she lives two lives, because half the family has accepted Scott back and other half hasn't," says an insider of Disick, 27, the father of Kourtney's 8-month-old son, Mason.

In one corner, Khloe, 26, leads the critical crew comprised of mom Kris Jenner and brother Rob. Meanwhile, Kim, 29, and stepdad Bruce Jenner feel therapy has redeemed Disick, who has also cut down his drinking.
"Khloe is always the bad cop, and I'm always the good cop," Kim told Us Aug. 9 at the Elle Girl Model Search shoot. "I've been through more relationships than Khloe, so I can understand what it's like to go through difficult times and still want to be with that person. Khloe is like, 'You f--ked up, you're out."

Indeed, "there have been knock-down, drag-out fights between the girls over Scott," a family insider admits to Us.
Both Khloe and Kim urged Kourtney, 31, to dump her beau of four years after one of Disick's partying binges ended up with him punching a mirror. "The whole situation frustrates me so much I want to scream!" Kourtney fumes on the Aug. 15 finale of Kourtney & Khloe Take Miami.
Khloe admits to Us she's "hard on" their relationship.
Even though Khloe and Kim will stand by their sister, they won't give Disick a break.
"There's a lot of them, so it's tough," pal Jonathan Cheban, star of E!'s The Spin Crowd, tells Us. "It's a lot of girl power and they attack."
