Pathological lying is defined as telling lies to the point they are persistent, extremely exaggerated and often told without a discernible reward. Psychiatrists have not given pathological lying the title of a true mental disorder as of yet, though this behavior is suggestive of a mental disturbance.

If you believe that your husband has something to hide, examining his body language, making eye contact and asking for details can alert you to holes in his story.
