It looks like the Kardashians are finally fed up with Rob Kardashian’s behavior – some of them anyway. Previews for an upcoming episode of “Keeping up with the Kardashians” shows Kim Kardashian, 34, ready to give up on her brother while Kris Jenner and the rest of the Kardashian clan attempt to stage an intervention. Kim complains that the family “does whatever he says,” suggesting that it may be time to “give it up.”

“It’s just like, at some point you just have to give it up. We all make his life so easy,” she says before calling the 28-year-old “pathetic.”

Another clip shows sister Khloé, who has always had a strong relationship with Rob, on the phone trying to convince him to seek help once more. The 30-year-old quickly gets emotional, asking if Rob finds it fair to put her through this once more. As you may recall from previous seasons of the show, Khloé and Rob lived together though much of his personal struggles. Rob was forced to move out of Khloé’s home, which she shared with estranged husband Lamar Odom, after claiming it was an unhealthy environment for him. He blamed some of his weight gain on the sweets she kept in the home for her former husband. Even after Rob moved out the two remained close, with Khloé often being the only family member able to get through to him.

The preview shows Khloé telling her family she thinks the intervention is a bad idea, calling it an “ambush” on both her and Rob. She is shown arguing that no one in the family makes an effort to see Rob and fears the intervention may cause him to “get pretty agitated.”

“I just feel like my mom and sisters are missing a major gap of attempts to help Robert before this drastic step is taken,” she said in a confessional interview.

Rob has been struggling with a number of problems ranging from weight gain to social anxiety. He has withdrawn from the public eye for the most part, resurfacing occasionally on social media.  Khloé recently told WonderWall magazine her brother was “not at his happiest place,” but said she remained hopeful he would get back there.

“I will always be his No. 1 supporter,” she told the magazine.

The latest episode of “Keeping up with the Kardashians” airs Sunday at 9 p.m. EDT on E!
