It's been a long road for Khloe and Lamar.
Khloe Kardashian remains by Lamar Odom's side at Sunrise Hospital in Las Vegas, where the former NBA player is being treated after he was found unconscious at the Love Ranch brothel in Crystal, Nevada, on Tuesday. Although sources tell ET that the 35-year-old has shown some promising signs, it's an uphill battle for Odom, who has also been joined at the hospital by members of the Kardashian-Jenner family, as well as ex-girlfriend, Liza Morales, and their two children, Destiny, and Lamar Jr.
ET was told on Wednesday that Lamar has been placed on dialysis after starting to experience kidney failure. Audio from the 911 call alleges that the former NBA player had cocaine and “enhancement” supplements in his system.

While Odom has received countless messages of love and support from not only his former Los Angeles Lakers teammates but across the NBA, his tragic story has been significantly exacerbated by the surname of his estranged wife: Kardashian.
Odom and Kardashian wed in 2009, and their complex relationship has included many ups and downs:

Odom marries Kardashian in September, just one month after they met. While Keeping Up With the Kardashians was a well-known reality show, the Kardashians and Jenners weren't nearly the ubiquitous media presence they have grown into today. As Kardashian begins to sit front and center at Lakers games, she starts getting a taste of the superstar athlete’s lifestyle, as Odom is at the height of his NBA career.
"This is my first NBA Finals so I'm excited," a wide-eyed Kardashian tells ET backstage at the NBA Finals in 2010. "It's an honor to be here, and to be able to watch Lamar."
The reality star explains that her basketball beau was handling the pressure like a "pro," adding, "He's a professional. Calm, cool, collected." The focus of the interview was Odom.

As Kardashian's star rises, the now 31-year-old stresses that she makes her own living separate from her NBA player husband. The couple starts to make a distinction between their own relationship and a "basketball marriage." "Khloe would tell you in less than 2.2 seconds she's not a basketball wife," Odom tells ET at a 2011 press junket for their reality series.
"I'm not just a basketball wife. I have my own career," Kardashian adds.

The couple is three years into what, at this point, is a celebrity marriage. Kardashian tells ET that she laughs about the days when it was all about Odom.
"It's so entertaining to me, when he was the first Laker to win Sixth Man of the Year [and] won two championship rings, no one commented about the TV shows," she admits at the E! Upfronts from that year.

Under the light of the evermore prominent Kardashian name, we begin to see Odom unravel.
2013
The couple's rise in celebrity sets the stage for their high profile divorce.
In August, Odom is arrested on charges of driving under the influence of alcohol. Odom pleads no contest. He is given three years of probation and ordered to complete an alcohol abuse treatment program. At the same time, the basketball player battles speculation about past issues with substance abuse.
Plagued by media scrutiny and struggles in their own relationship, Kardashian initially files for divorce in December. The proceedings since have been lengthy, and to this day, the divorce still isn't final.

In a 2014 episode of Keeping Up With The Kardashians, the reality star makes the bold claim that Odom was unfaithful while the couple was still together.
"Let me tell you something -- last year on my birthday, I lied to everyone, because I had to lie and say I was with my husband, when in fact my husband was missing with another girl, OK?" Kardashian yells. "And I lied, and I gave up my Beyonce tickets to Kendall, that's how badly I was hiding. And I didn't have a birthday, I was alone, and lied to everyone."

Despite the signing, their relationship seems to be in a good place, with Kardashian telling Complex magazine that the two still talk.
"I talked to Lamar this morning. I talk to Lamar as often as I can, which is inconsistent, but not on my terms," she shares. "When you genuinely feel like that was the right relationship, you’re supposed to give it all you can. That’s what marriage is about. It’s not, 'Let’s see if it works, if not we always have divorce.' I am not one of those girls."
"I miss him every day," Kardashian admits. "I miss what we had -- things we got to do together are just memories. I like looking back and holding on to that stuff."

"[Khloe] asks that you continue to keep him in your thoughts and prayers and for the media to respect his privacy during this difficult time," the source adds.
While she and Odom's lives are demonstrably different from their whirlwind beginnings back in Sept. 2009, one thing remains -- these are two people who care deeply for one another.
