On Monday, ET's Kevin Frazier spoke with Kardashian at a signing for her new book Strong Looks Better Naked in Los Angeles, and the 31-year-old reality star opened up about Odom's health and their relationship.
"He’s doing better every day, for sure, which is a blessing, but it’s going to be a long road and he has to walk that road," Kardashian shared. "It's going to be a long time."
Odom was hospitalized in October after he was found unconscious in a brothel in Nevada. After spending some time at Sunrise Hospital in Las Vegas, the 35-year-old former NBA player was airlifted to Cedars-Sinai Medical Center in Los Angeles. Kardashian has been by his side the whole way.
Kardashian confirmed as much to ET, explaining, "I’m married for a multitude of reasons, but it’s not intimate reasons. It’s more for medical and also to help with a lot of other things to do medically."
"With his mental strength and everything like that, it was the best choice to make at the time," she added.
Kardashian admitted that she believed many people are "really confused" about the nature of their relationship, and how long it will take for Odom to heal. However, the Keeping Up With the Kardashians star emphasizes that Odom has a number of obstacles to tackle before the issue of their marriage even comes into play.
"Even if he was 100 percent better, he has a lot of other issues he has to deal with, I think, before taking on any relationship," Kardashian said.
Opening up about substance abuse issues, Kardashian said she can "totally understand" what can lead people to addiction.
"When you are in pain and hurting elsewhere in life, you use certain substances to try to block out that pain. It’s really easy to do that and you think that's going to be your cure," said Kardashian. "[But] at the end of the day you have to address the problem at hand because the alcohol or the drugs is not going to take that problem away."
Kardashian also said that, in the past, she's turned to liquor to cope, telling ET that her issue "was more [with] alcohol."
It's a subject she gets candid about in her new book, where she recounts her own experiences with getting drunk to deal with the death of her father, Robert Kardashian, Sr.
Despite her past excessive partying and drinking, Kardashian reveals that she never ended up having to go to rehab because her sister Kourtney "put her foot down and forced me to take control of my life." For more on her story of binge drinking and her brush with rehab, check out the video below.
