"I just don't want to put up with people that you want to be monogamous but then you're not monogamous," Kardashian said. "I always said, 'It's long distance. We don't need to be monogamous. There's a lot of [expletive] going on in both of our lives.'"
"What girl says that and the guy says -- why wouldn't you say, 'Okay, that's great!' instead of forcing a relationship [and saying], 'Let's be committed, let's be committed,'" the star asked. "He wanted that. I wanted it, but I wanted to be realistic."
Kardashian and Harden were first linked in July and carried on a long-distance relationship between Los Angeles and Houston. The NBA star supported Kardashian's relationship with her estranged husband, Lamar Odom, but allegedly ended up cheating after seeking commitment.
"He sought me out, he wanted to be committed. Then he wasn't committed. So Koko had to go-go," Kardashian said. "[At first] I was like, 'Great, this guy is in it for the long haul, let's do it.' I found out he wasn't. And I got the receipts to prove it."
Kardashian and Odom's divorce was pending when the 36-year-old former NBA star was discovered unconscious in a Las Vegas brothel. The reality star called off their divorce during Odom's subsequent hospitalization, but said they aren't back together Tuesday on The Talk.
"We're not back together," she confirmed. "I didn't want for our divorce to happen, but it happened for many reasons and that doesn't mean I just forget about this person. I still believe in my vows of being there for him. I know it's confusing. It's very confusing. It's not a romantic place."
