The choice of a marriage therapist is a very serious matter. Some of them are pro-marriage, capable of maintaining civility during sessions, and push both parties to try to work out their problems but in a neutral, unbiased fashion and without ordering the patients to take drastic actions. Such therapists can be a great asset. They will listen to both sides objectively, tease out inconsistencies, get people to open up about their real problems and issues, and enable progress towards resolving the problems. The best of them even gradually teach their clients how to do these things themselves.
However, if you pick a poor therapist, you may rapidly find that not only will your marriage be destroyed, you may also end up with losing contact with your children and/or false criminal allegations against you. This is particularly a problem for men, but can happen to women, too.
A poor marriage therapist can destroy your marriage and create a “death spiral” out of your life.
