The recent thread by theFed made me think of this question, especially in light of the Arnold and Maria scandal. What if your spouse cheated? What if it was a one time indiscretion? Does it matter the circumstance? For the ladies, what if a seductress initiated the physical contact with your spouse? Assume that the marriage is an otherwise great marriage with lots of love and respect. Frankly, I am puzzled why Maria would choose to leave Arnold for something that happened so long ago supposedly by a woman who set out to seduce Arnold. Did she make that decision because she is concerned about what others would think if she stayed? Maybe the marriage was not a good one to begin with. I don't see myself remaining in a marriage with someone that's a cheater but I am not sure if I would want to throw away my marriage of many years for a one time indiscretion particularly one with small children.
