(Yahoo!) - Things aren't looking good for Khloé Kardashian and Lamar Odom.

According to a new report out of People magazine, the "Keeping Up With the Kardashians" star and her troubled NBA player husband appear to be at an impasse in their relationship.

"They're separated for the moment," a source reveals. "Khloé is spending many nights at her mom's house and Lamar is at his place [in] downtown [L.A.]"

"The whole situation is so sad," another friend of the family explains. "She wants to save her marriage, but Lamar doesn't and he's not in his right mind to do so. So what can Khloé do?"

A third source echoes: "I believe Lamar is the one who wants out [of the marriage]. It's not looking good."

On Friday, Lamar was charged with one count of driving under the influence. He faces a maximum sentence of six months in jail and a $1,000 fine if he's found guilty.

While Khloé continues to put on a brave face on social media, behind closed doors, sources tell omg! the 29-year-old is rightfully devastated.

"She's done everything she can do to try and help [Lamar] in hopes to save their marriage," one source close to the family says. "It's just heartbreaking. There really is nothing else she can do."

While Odom, 33, continues to live apart from Khloé, she is leaning on her family and friends for support.

"Whatever happens, everyone is behind her," a second source tells omg!. "It's this weird waiting game. No one really knows what is going to happen [with their marriage], but it's hard not to imagine divorce being the only option."

Odom is due in court on September 27 … which just so happens to be his and Khloé's fourth wedding anniversary.
