The therapist must be there for the couple, and not for either member of the relationship. The couple must bring to therapy only a commitment to try it out. Relationship therapy has helped many people. It can be a profound developmental experience for one or both members of a couple. But, there are no expectations that any relationship will be fixed because of therapy, only a realization that without therapy, there will continue to be suffering and lack of understanding in the relationship.
Every couple presents a unique situational problem or relational dilemma.

However, arguments are probably the number one problem I have heard from couples seeking treatment. This is not surprising since arguments can be damaging, hurtful, searing, and unfair.
