Couples counseling is not the same as individual counseling. Most therapists do not acknowledge this and include couples counseling among, sometimes, 30, 40 or more speciality areas of their practice. Many of these therapist have not completed any courses or had any supervision in couples counseling.
Couples counseling often times includes comples issues such as substance abuse or addictions, infidelity, behavior addictions (pornography, cybersex, sex, love, food, etc.). It is important for couples on the brink of divorce find a therapist that is skilled in facilitating these difficult areas. When shopping for a therapist that engage in couples counseling ask them about their training, experience, areas in which they practice the most, and their approach to couples counseling. Don't wait till you are up against the wall to avoid picking a couples counselor in a panic.
