Infidelity: Putting Monogamy Into Question in Revolutionary Road

I think that monogamy is artificial. I do not think it's something that comes naturally to us - Tom Ford

Is there a perfect model for a monogamous relationship and if so, how do we construct it? Frank and April Wheeler in Revolutionary Road present a cold, disturbing look into the ideal American Dream: the husband, wife, and kids residing comfortably in their serene neighborhood adorned with white picket fences and lush greenery. But something about this security, this monotonous, routine lifestyle drains the excitement and intense passion igniting the love between Frank and April. Revolutionary Road suggests that sexual exclusivity and a constricting sense of fidelity are in fact inhibitors of commitment to our partners. Infidelity, it seems, is not a matter of questionable morality or disloyalty, but is motivated by a desire to be liberated from the restrictions presented by monogamous relationships.
