Khloe Kardashian opens up about her marriage to Lamar Odom in her new book, Strong Looks Better Naked, which doesn't hold back any punches about their struggles.

According to Page Six sources who have apparently read it, the book details a three-day bender that justifies Khloe's decision to file for divorce two years ago, although the divorce was never finalized.

"The thing is, you can't control other people, and you can't control the outcome of situations," Khloe writes in the book, "and if you think you can, you will soon discover that you are sadly mistaken."

Their marriage hit a rough patch when the couple moved to Dallas after Lamar was traded from the Los Angeles Lakers to the Dallas Mavericks in 2011.

In the book, Khloe writes that every time she went outside, paparazzi hounded her with questions, asking, "Is it true Lamar cheated on you?" and "Is he doing drugs?"

"Every day felt like an attack," she writes. "It was also humiliating. It got to the point that leaving my house would give me social anxiety."

In 2001, Lamar, whose father allegedly struggled with a heroin addiction, violated NBA drug policies twice in eight months for marijuana use. He later apologized during a press conference, saying, "I've made a couple [of mistakes] and I may make a couple again, but hopefully they won't be as big as this one."

ET can confirm that Strong Looks Better Naked, out Nov. 3, was printed weeks ago, prior to Lamar's hospitalization. Khloe has remained by Lamar's side since Oct. 13 after the NBA champ was found unresponsive at the Love Ranch brothel in Crystal, Nevada.

According to Page Six sources, the book ends with Khloe thanking Lamar for some of the best years of her life: "Before I met you I felt invisible, and after I felt seen."

On Wednesday, Khloe's lawyer, Laura Wasser, filed to have the divorce papers withdrawn, a clear indication that the couple is willing to give the marriage another try.
