Practicing Monogamy in Relationships

In today's society, monogamy is very challenging. With polygamy shows such as Sister Wives and the fact that many people are not getting married,mongamy is being challenged. Given that many partners cheat on their spouses, married or not, monogamy is further challenged. I want to discuss if monogamy is a myth in today's society. If you are Christian or moral, there may be some reins.
