As hard as Kim Kardashian tried, her 72-day marriage to Kris Humphries couldn't have been further from a fairytale, and on Sunday's season finale of Kourtney and Kim Take New York, the 31-year-old reality star realized that the hard way.

Forced to confront NBA player Humphries, 26, in their final days in the city, Kardashian attempted to reconnect with her then-husband, but in the end, her bitter attitude got the best of her.

"Sometimes I feel so dead inside because I haven't really been myself here. I feel like we went from so much wedding stress and came here a couple of days later. It's definitely been a lot to deal with that I don't think I was really prepared for," she told Humphries during an emotional confrontation with her beau, who agreed their relationship "got a little lost in the shuffle."

Later, after Kardashian freaked out over Humphries moving his belongings into her home in L.A. and Kourtney called her a "bitch" for her behavior -- the reality star reached her breaking point.

"I invited all these people to this huge wedding and flew everyone out, wasted everyone's time and everyone's money -- everyone's everything -- and I feel bad! At 30 years old, I thought I'd be married with kids and I'm not. I failed at this," she tearfully told Kourtney, 32, during a wide-ranging meltdown that also included a phone call to sister Khloe, 27.

"I feel awful that I made him move out here and change his whole life. I feel sad, I feel bad for the guy. He fell in love with me and I fell in love with him and now all my feelings have changed," she bawled.

While Humphries was the one to actually contemplate a divorce on Sunday's finale during a conversation with a pal, it was Kardashian who filed papers on October 31, shortly after filming wrapped.

"These past couple months have been such a growth experience for me. I just feel like I always had this vision of what my life would be like," she reasoned when packing her bags to leave New York City. "I wanted babies and this fairytale. I wanted to be married by 30 and everything I envisioned my life to be is not really the fairytale I wanted it to be."
