Many of the signs of a problem in a marriage are non-verbal and can be detected by observing body language. A couple which has very little eye-contact, and displays no outward signs of affection may be in trouble. When there is a general apathy and lack of excitement about each other this can be a sign of a problem between them. Couples who no longer enjoy each other’s company, and prefer to pursue separate interests and hobbies, are probably drifting apart. When a spouse makes sarcastic or derogatory remarks about his or her spouse in company, whether or not the spouse is present, this is usually a sign that there is a problem in their marriage.
