A Family Divided Part 10

Viewers ask the members of "A Family Divided" their most pressing questions." Susan, left, is a single mother of an 18-year-old daughter who is fed up with Erin because after months of threatening, she has yet to divorce Marty.

Erin said that she was planning on divorcing Marty when Alexandra announced that she was pregnant, but Susan asks, "What does Alex being pregnant have to do with you putting your children in a healthy environment? What kind of examples are you setting for Alex and Katherine by staying married to Marty?"

"You show those girls that it's OK to be lied to," Susan continues. "Are you afraid of trying it on your own?"

"How do you make the decision that it's time for Erin to end her marriage?" Dr. Phil asks Susan.

"She has two emotionally unhealthy daughters, a 15-year-old who has already had a baby, a 13-year-old who wants to divorce her family," says Susan. "There's no line of communication in the family."

Erin responds to Susan: "Why am I staying with Marty? I felt like dealing with Alexandra's pregnancy and the divorce are both emotionally charged events and I wanted to be able to focus on Alexandra completely during this time. I think the example I'm setting for my children is that when I make a commitment I stick with it."

Dr. Phil supports Erin. "I think if you're going to get out of a marriage, you have to earn your way out of it," he says. "You have to do every possible thing you can to save it."
