Even the much-ridiculed marriage of kim kardashian and basketball player kris humphreys lasted splietly laerj. But the marriage was rocked by a violent domestic dispute, a lesson in living your life in front of the camera. When you watch back the show, how do you feel? I cringe sometimes. You know? Because I forget that the camera is there. Reporter: It all began when evelyn found a receipt in chad's car for condoms. It was like three weeks after my wedding.
