Khloe Kardashian and Lamar Odom Divorce News Saddens NBA Star

Lamar Odom is reportedly hurt by the news of his estranged wife Khloe Kardashian's decision to officially file for divorce.

"He's deeply saddened by Khloé filing for divorce," a source close to Odom told E! News. "He knew it was coming and it was only a matter of time. He felt like he gave his all to try and save the marriage, but ultimately he wasn't able to."

Odom, the 34-year-old NBA free agent, has made headlines in recent months for allegedly stepping out on his marriage and battling with a drug addiction. While numerous media outlets have speculated about the possibility of the 29-year-old "Keeping Up With The Kardashians" star's marital woes, she officially filed for divorce due to irreconcilable differences Friday, according to The Hollywood Life reports.

While E! reports that the pair have been living apart since the summer and undergone counseling, the source said Odom still cares about Kardashian.

"There will always be a place in his heart for Khloé," the source told E!. "He will always love her and her family. She has decided and there is nothing more he can do. He has to accept that."

Kardashian revealed some struggles within her marriage on her "Keeping Up With The Kardashians" reality television show. While Kardashian never detailed exactly what was wrong with Odom aside from him being in a "dark place" and needing help, her 26-year-old brother Rob Kardashian offered her some advice after revealing that he would move out of the home she shared with him and her husband.

"All you can do is pray and keep trying if you want to try," her brother Rob told Khloe on their show. "If have to let him figure it out."

Khloe revealed that while she has struggled with Odom for years, things have gotten progressively worse over the course of her four year marriage.

"A lot has been going on the past couple years just with me and Lamar and I made that choice just to keep that in my marriage," Khloe revealed in her individual confessional moment on the show. "But lately it's getting bigger...sometimes things are bigger than yourself."
