Just think how many marriages could be saved if each person in a marriage had this courage: “How many of us have the courage to tell our partner “Look, I’m feeling tempted” or “I feel like we’re drifting apart”? You are right to point out that the discussion alone will not keep marriages together. If done before acting, it might permit either dealing with the problem successfully or it might lead to both concluding the breach was too great. A couple might have been right at one time, but grew apart. A divorce under those circumstances would be hard-but far less emotionally damaging.
