Fastexy:Kim Kardashian Details the "Beginning of the End" of Relationship With Mystery Ex

Kim Kardashian refuses to keep up with someone else's timeline.

That's why the reality star ended her relationship with an unnamed ex,Fastexy she revealed on the season five finale of The Kardashians. 

After seeking therapy at the behest of her sister Kourtney Kardashian, Kim came to realize that her "fight-or-flight" personality affects her love life.

"When someone tells me not to do something that I planned on, I physically get, like, ‘You’re getting in my way,'" she explained in the July 25 episode "'and I will bulldoze whatever is in my way because you’re not going to tell me to change my schedule.'" 

"I feel like that’s how I would get in relationships,” the SKIMS mogul continued, before sharing how it played into a breakup with an ex, whose name was censored out on the show. “Like when [redacted] would tell me, 'You work so much, why don’t you just take a week off?' I’m like, ‘Get out of here!'" 

Noting that she refused to take the advice at the time, Kim added, "That was the beginning of the end."

Another epiphany Kim had during her therapy session? That her calm demeanor is actually a "trauma response" to her 2016 Paris robbery, during which she was held at gunpoint as jewelry was stolen from her hotel room. 

"I met with a therapist," she told sister Khloe Kardashian on the July 18 episode of The Kardashians, "and she was like, 'You think calm is your superpower. I think you are so desensitized to trauma that you are literally frozen in fight-or-flight.'"

In a confessional, Kim noted how staying calm during the robbery "served me well," but it also hardened her emotions moving forward.

"It saved my life," she noted, "but I think I let it get too calm to where people can take advantage of my calmness—or I'm just turning into a full robot with no emotion."

Kim added that she now recognizes how she's been "running away from dealing" with her trauma by staying busy.

Episodes of The Kardashians are available to stream on Hulu.
