There are many reasons why a spouse will cheat which are: the person who cheats may have come from one or both parents cheating; low self esteem; insecurity or vanity; addicted to sex; lost communication skills with his spouse; wanting to see if they are still attractive to the opposite sex; bored in their marriage; not able to commit to their spouse or anyone else, etc. The psychologist gets to the root of the problem as to why, in this case, the husband feels the need to cheat, but is not there to give the husband a lecture.
