Proverbs 15:22, “Without counsel purposes are disappointed: but in the multitude of counselors they are established”
Sometimes it helps to have a good relationship coach. Family and Marriage Counselors and Psychologists are highly educated and helpful for analyzing and understanding problems, how to prevent them, and how to manage them. But often they are more helpful before problems get out of hand and are not focused on pulling a troubled marriage out of crisis and saving a marriage.
However, a coach can often help in a crisis, too. Yet you have to be careful because some are really good and some can do more harm than good. Do your research.
