The reality couple stunned fans this week by announcing their separation, but insisted they would remain friends.
Speaking to People, 57-year-old Kris said of their current relationship and the future: "It's just not something that's real negative and nasty. 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."
Kris also said she couldn't think of any one thing that went wrong between them, saying: "I just think it has evolved… We're just happier now."
She echoed his thoughts in a chat with TMZ, saying it was an amicable split and the couple remain "best friends" and chat every day.
As for whether they'll reunite, she replied: "We're just happier living apart."
Kris and Bruce have been living separately for quite some time. It was actually rumoured earlier this year that their marriage was on the rocks after it emerged Bruce had been living at their second home in Malibu.
At the time neither revealed any issues in their marriage.
Kris' close friend, US TV host Kathie Lee Gifford, spoke about the separation on Today earlier this week, saying she hopes the pair can reconcile.
"They do not have a pre-nup and neither has met with a lawyer yet… There will be a lot of money to divide up if they end up doing that," she said.
"I hope for the family's sake they'll be reconciled. They do love each other and have a lot of fun together. I think they've just been under such unbelievable pressure. So many things going on, so many products."
Kathie-Lee, who is godmother to Kris and Bruce's daughters Kendall and Kylie, added: "Last time I was at Kris' house in every different room of the house somebody was meeting with somebody about a new deal. If it's always about a deal going on and you can't find someone in your house because there is so much going on, it's just gotten out of control."
Kris and Bruce will both continue to film Keeping Up With The Kardashians, with reports suggesting the series will cover the split.
