Rebecca and Josh are at a crossroads in their relationship. The parents of an 18-month-old and a daughter on the way say they argue often and can’t get on the same page when it comes to taking care of the house and the family.

TELL DR. PHIL YOUR STORY: Is unbelievable drama dividing your family?

Rebecca says Josh is a “controlling narcissist” and that she feels like nothing she does is ever good enough for him. Although, she says she hopes to marry Josh one day and wants to know if they can mend their relationship.

Josh says that he is the “breadwinner” and his girlfriend of two years is the “housekeeper” but she needs help learning how to do her “job.” He says he’s not ready to walk down the aisle with Rebecca now, but “once Rebecca learns to be a better wife and mother, I think the sky’s the limit.”

After Josh reveals to Rebecca that he wants to separate, Dr. Phil weighs in with his thoughts.

“I think you two being apart for a period of time is not a good idea; I think it’s a great idea,” Dr. Phil tells the couple. “I think that you two have mutually defined a very toxic relationship and environment, and your children are picking up the tab for that.”

To Josh, he says, “You need a new definition of the role of the man in the family. You have some personality characteristics that are getting in your way.”

To Rebecca, he continues, “You need to require more in your life. You need to require that you’re treated with more dignity and respect. You need to require that you have stronger footing in this relationship, that you have a voice, that you have freedom, that you have independence. You’ve got to redefine this.”
