Kardashian told the hosts of Australia's "Sunrise" program on Thursday that she followed her heart and felt there was no right or wrong way to handle the demise of her brief marriage to pro basketball player Kris Humphries.
The reality TV star filed for divorce on Monday from Humphries after just 10 weeks of marriage. Critics have accused her of marrying Humphries in a lavish made-for-TV ceremony as part of a money-making publicity stunt.
Kardashian says she is hurt by such suggestions.
Kardashian and her sister Khloe are in Australia to promote a line of handbags. The 31-year-old reality star also posted a message to her fans on her website Tuesday, one day after filing for divorce from Kris Humphries, whom she married in a lavish ceremony that aired as a two-hour TV special on E!
Kardashian says that while she "married for love" and "would not have spent so much time on something just for a TV show," she admits that she "got caught up with the hoopla and the filming of the TV show."
"When I probably should have ended my relationship, I didn't know how to and I didn't want to disappoint a lot of people," she writes.
Kardashian says she takes "full responsibility for my actions and decisions," adding "it just didn't turn out to be the fairy tale I had so badly hoped for."
"I want a family and babies and a real life so badly that maybe I rushed into something too soon," she says.
Kardashian and Humphries dated for nine months before marrying in August.
She goes on to say that reports that she made millions of dollars off the wedding "are simply not true and it makes me so sad to have to even clarify this." Twitter and Facebook were filled with anti-Kardashian sentiments on Tuesday, including some photos that were reposted thousands of times.
One photo showed the happy wedding couple gazing adoringly at each other above large type that read, "If you think gay marriage cheapens the institution, two words... Kim Kardashian."
In her post, Kardashian says she plans to "donate the money for all the gifts to the Dream Foundation."
The couple's $172,000 wedding registry included such items as a $1,650 coffee pot and two $1,250 sterling silver vegetable spoons.
Kardashian does not mention Humphries in the 370-word message.
