When Is It Time To Walk Away From A Marriage?

Sarah and Ed have been married for 20 years, but distrust and dysfunction have taken over their lives. See why here. Ed, who admits he's had emotional affairs with other women but insists the relationships never became physical, has been to rehab for sex addiction — but his wife still struggles to trust him.

Dr. Phil tells Ed, "If this is a life sentence, you ought to run ... If there's nothing you could ever do to vindicate yourself, then you ought to run."

When Ed says he won't leave his wife and children, Dr. Phil advises, "Then you need to man up and plug in ... Look your wife in the eye and say, 'What can I do today to make your life better? I ran this off in a ditch. I'm going to do what it takes to get it back on the road.'"
