The reality star says her brother fell into a "deep, dark place."
Khloe Kardashian has admitted to being the nurturer of her famous family, but in her new memoir, Strong Looks Better Naked, the 31-year-old reality star says that her catering to Rob Kardashian's needs wasn't best for her brother.
"I was doing everything in my power to try to help him, and my entire family accused me of being an enabler," she writes. "I was the only one who was there for him, I said. They didn't care. None of that was true, of course. They all cared."

Khloe says that she began to realize that she was "making life too easy for Rob."
"I was constantly checking up on him, making sure he had the food he liked, seeing if he needed anything from the store, asking what I could do to make him more comfortable," she recalls. "My sisters said I was babying him and that he'd never leave the house if I didn't let him fend for himself. I argued with them because it was an emotional issue, and emotion tends to cloud your thinking."
While the Keeping Up With the Kardashians star confesses that she's enabled her reclusive brother, who still lives with her, she's still not ready to put him "out on the street on the off chance that he will make an effort to change his life."

In the chapter titled "Make the Best of Everything," Khloe calls out her brother when talking about people who whine about their lives and don't take proactive steps to change their situation.
"Take my brother Rob," she wrote. "I love and him and he knows I love him, but he fell into a deep, dark place and couldn't find his way back."
Khloe says her 28-year-old sibling would try to "fix things his way" and would dive "headfirst" into quick-fixes. She gives the example of him attempting to get back into shape but giving up after just three weeks. "It was a waste of time," she recalled. "The truth is, he wanted too much too soon, and his unrealistic explanations totally short-circuited his efforts."

She's also resolved that she can't fix Rob. "He will make changes in his life when he is able to motivate himself," Khloe said. "And as much as I wish I could light that fire for him, I now see that the chances of that happening are slim to none."
In August, Kris Jenner told ET that Rob was back on track. "He's doing terrific. Robert's good," she said. "He's working out and eating [well], so he's on a good path right now."
