A lot has been said about what may have caused Kris and Bruce Jenner to separate after 22 years of marriage, but in a new interview, the Kardashian matriarch, 57, said that even she isn't sure.

"I don't think it was the pace of life. We've always gone 150 miles per hour, and Bruce has more energy than anybody," she told People magazine. "I just think it has evolved. I really can't put my finger on it. We're just happier now."

Bruce, 63, agreed, and recently said that "there's no animosity" between him and his estranged wife. She also said that since Bruce began spending more time at his home in Malibu, the couple's relationship has improved. In fact, Kris referred to the arrangement as "the best of both worlds."

"There was a definitely shift in the way we treated each other," she said of Bruce's move. "We will always be the best of friends, because that's the dynamic of our relationship. We definitely get along as a family and with the kids. We're so connected in that way. We love each other."

The couple, who have two teenage daughters together, and eight children between them from previous relationships, will continue to co-parent and prioritize their family, Kris said.

"It's a very wonderful dynamic. It's just not something that's real negative and nasty," she insisted. "I love really hard, and the people that I have in my life that I love will always be in my life forever. It's ultimately like one big happy family."
