"I think he just needed a break," Khloé told host Andy Cohen at the time. "I think also a lot of his personal relationships, really, it's not so much about physical appearance, it's a lot of how he felt internally about some of the women in his life and how they treated him, or how he felt they might have used him to get to certain areas or levels."

"And I think that really affected him because my brother is such a lover and has, like, the most incredible heart and personality," she continued. "And I think he's just getting stronger, and I think you have to get heartbroken and you learn from your mistakes."
