Khloe Kardashian didn't want to be monogamous with ex James Harden

Khloé Kardashian and James Harden’s relationship ended because he cheated.

“Koko had to let him go-go,” the svelte Kardashian, 31, revealed in a preview of Wednesday’s “Kocktails with Khloé” episode.

“I don’t want to put up with people — you want to be monogamous but then you’re not monogamous,” she said. “I’ve always said it’s long distance … we don’t need to be monogamous. There’s a lot of s–t going on in both of our lives. You live in Houston. I live in L.A. Let’s see each other, when we see each other.”

Kardashian says they “forced” their relationship despite their obligations keeping them apart — including her nursing estranged husband Lamar Odom back to health.

The pair began dating in the fall of 2015 and called it quits in early February.

“I got the receipts to prove it,” Kardashian slammed the Houston Rockets player.
