If there is an order in the custody agreement that says he can't take her out of state without consent of the ex-wife, then legally she can file a grievance with the court, or call it kidnapping but if she gave consent then changed her mind, I doubt a judge would file charges against him. Sorry that is such a hard situation. It depends on what you think she will do.
If it is not in the custody agreement, then there isn't anything she can do except add it in for next time.
