Marriage coaching is good for anyone, even if you are in a healthy relationship. Most people want marriage coaching so the counselor will fix the other person, but that does not work. The best reason to go to marriage coaching is to answer the question “how can I be a better spouse?”. Even if the marriage is over, a marriage coach can help you be a better partner in the next relationship.
Counseling/coaching is not about fixing others; it’s about self-growth.
