Any therapist worth their salt will tell you that not everyone is a candidate for therapy. In a situation where both partners have an interest in working to make a better marriage, I doubt that many people would say that they should get divorced. However, in a situation where one party is too self centered to acknowledge that they have a problem and carries on with attitude and behavior that speaks of lack of concern for anyone else (even those whom they profess to love), that person is not a candidate for therapy (and would likely never agree to go).
“There are a lot more appropo fixes.”
Aside from therapy, could you please elaborate.
