Openly Dating While Secretly Married: How Can You Spot A Cheater?

People get married all the time, but not everybody really understands what its all about, because, lets face it, where are the rules, guidelines, instruction, and training that is taking place in the homes? There is none, so the most people think is that marriage gives you a regular sex partner you can live with and hang out with sometimes and have fun. If you have children, you can raise them together. But sometimes, one person gets tired of "playing house" and decides to go and live another life somewhere away from home where they can pretend to be single again and enjoy dating again. Unfortunately, the new love interest has no clue that they are involved with someone who already has a spouse. This is the worst kind of deception, yet it happens too often. What is the root cause of lies about being married? Are we not teaching the spiritual foundation and purpose of marriage? Are we failing to define it as more than just having a convenient sex partner? Are we making fidelity difficult by not acknowleging the tremendous imbalance in numbers between single men and single women? Would legalization of Polygyny help? Or are men too stuck in the irresponsible, immature "player" mode to even comprehend the respectful system of polygyny? Are women too jealous and possessive to consider it? How do we make the dignity, honor and honesty of marriage a common cultural value?
