Instincts of Fidelity

"As Humans our emotions are just as much a part of our health as our diet and living conditions"

     Is Monogamy a human instinct?  I say its not, but with that said I know that monogamy is a lifestyle that if practiced, will lead to stability for the subsequent generation (assuming that the parents will be supportive and nurturing to their offspring).  Hhhmmmmm...
Why would monogamy not be an instinct?  From a primal standpoint it is instinctual that the few, strongest cluster of males offer the best support and protection to females (while passing on superior physical genes....this creates greater fitness variance).  The weakness in the genetic pool for that species naturally dies out under these terms.  That is instinct, wipe out the weak, empower the community with a strength to maximize the possibility for growth.  Fair?  Not so much, but who says life is fair...its about survival.
But we are Human, we have a conscious that we share...we verbalize it, document it...we like to "discuss" things.
This means that monogamy becomes a learned behavior...making us one of the few species that are taught to be monogamous as adults.  There are exceptions (individuals that never marry but have relationships, marry multiple individuals concurrently or consecutively, or there are open relationship arraignments).  Just as an aside, even if BOTH partners claim to be OK with open relationships...jealousy and depression will eventually find their way between these partners...this ultimately will create some sort of animosity and mistrust.
    Where is this discussion headed for?  A Discussion and evaluation of personal  Discipline!?  Yes, of course that factors into this.  Personal happiness?  It is important to satisfy the self, that in turn will exude the positive individual one can be...but how will happiness be found and at what price...at who's expense?  Examination into  Self control?  That too is an element...but if you truly love someone, you will naturally possess that loyalty necessary to remain faithful...if your faith is in question, then perhaps your selection of mate may not be your ideal match.  When you find someone important enough to you, you will naturally discover how easy discipline becomes to stay monogamous.  Monogamy does go beyond a personal boundary because it affects the entire dynamics of a family.  Since it takes a long time for offspring to fully mature...When partners stay monogamous they ensure that the survival of their progeny takes its course with the resources to attract mates of their own.  In polygamous scenarios, that survival may get compromised...and if it does not, then surely those necessary resources beyond development will certainly diminish...potentially minimizing your offsprings chances of attracting a mate.  It goes beyond any moral implication...deeper then any thought, feeling and behavior any one individual may experience in their environment...Monogamy is a selfless act to protect your mate and your children!  Now therein true strength!
