Your therapist’s primary goal should be to concentrate on helping both partners to solve the problems in their relationship and not encourage a split when things get tough without trying this first. Feel you can ask what percentage of couples actually manages to repair their relationship after marriage therapy and if clients leave happy no matter what the state of the relationship after therapy. They might not give a direct answer but their reaction will tell you volumes. You should have confidence in your therapist to help your relationships problems aid you in remaining together.
