Karla claims her husband Stephen has lied to and manipulated her throughout their 38-year marriage – usually so subtly that she thought she was the problem. Stephen admits he has lied and played mind games with Karla, but when it comes to questions about his past, he says he doesn’t remember – like whether or not he ever planned to marry another woman. Could there be an explanation for Stephen’s claim of memory loss? And is Karla’s quest for the truth really going to improve their dysfunctional relationship? Watch as Dr. Phil gets to the bottom of this troubled marriage.
