Revealing all in a new sit-down TV interview, Kim Kardashian has told Oprah Winfrey that she became depressed after realizing her marriage to Kris Humphries was a mistake in a join interview with members of her family that aired on Oprah’s Next Chapter.

“I was in such a deep depression I thought I was going to back away from it all,” the reality TV star said of her 72-day marriage. “You know when you just have that feeling that he’s the one? When we moved in, I had the feeling he was not the one.”

Despite her short marriage, Kim insists she has no ill feelings for her ex. “He’s a good person. I will always have a place in my heart for him. It just wasn’t for me,” she said.
