It’s easy to tell when a couple is under the influence of Dopamine, the brain neurotransmitter that is released whenever we experience pleasure. They behave like drug addicts; perpetually on edge, waiting for that next hit, or the next text message from each other.

Just like the lab rats in that famous lab experiment, humans become addicted to whatever (or whoever) causes a rush of Dopamine to be released in our brains.

And when the Dopamine fades, it usually leads to a spectacular break up. Take Khloe Kardashian and Lamar Odom, for instance. At one time they ouldn’t get enough of each other. But now, according to Radar Online, Khloe has come to her senses and kicked Lamar out of her mansion for cheating on her.

From Radar Online:

In the days before Khloe Kardashian booted Lamar Odom from their mansion, she first exiled him to a separate bedroom as their marriage unraveled, RadarOnline has learned exclusively.

The divorce drama, first reported by Radar, unfolded as Khloe lost her trust in Lamar, worried that he had been cheating on her. And she had good reason to worry. Lamar has been cheating on Khloe for months, according to Star magazine’s new issue, which reports the NBA player carried on a year-long affair with Jennifer Richardson, a 29-year-old brunette he first met at the Stadium Club strip club in Washington, D.C.

Khloe and Lamar’s marriage has been troubled for a long time, a source told Radar.

“Things have been very, very tense in the house for a great deal of time,” a source close to the couple told Radar. “Khloe kicked Lamar out of their bedroom several months ago and he was sleeping in one of the mansion’s guest rooms.

“She fears Lamar has been cheating on her with various women. It really irked Khloe when Lamar was blatantly caught going to a strip joint.”
