The 31-year-old socialite filed for divorce from the basketball player on Monday (31.10.11) after just 72 days of marriage and says her "intuition" told her it was the right thing to do.
She said: "I think when you know so deep in your heart that you just to listen to your intuition and follow your heart, there's no right or wrong thing to do."
Kim is currently on a business trip to Australia with her sister Khloe and brother-in-law Lamar Odom and admits the pair are helping her cope with the split.
She told breakfast TV show 'Sunrise': "I really wanted to stick with my commitment to come out to Australia. I love the fan base here.
"I did want some time to myself but I don't want to bail on everyone and skip out on this commitment here.
"I've got Khloe and Lamar here and we're just getting through it."
Khloe added: "I'm really proud of Kim for not bailing. She's being really strong. Lamar and I are here to be her support."
Meanwhile, Kim's mother Kris Jenner revealed the whole family were saddened when they realised the marriage was going wrong.
During an appearance on the 'Today' show, she said: "It's just our job now to wrap our arms around her through thick and thin.
"It certainly wasn't for TV. We have enough going on with our show that we don't have to make things up. She felt that she was in love with him. It was an amazing time ... I had no idea there was a problem at the time. It saddens all of us."
