Thanks to Her Highness Winni, she prompted this. The sexes do not see eye to eye on the subject of faithfulness. Men see sexual infidelity as the worst offense to them. Women see emotional infidelity as the worst to them; they can tolerate sexual unfaithfulness if they are sure no emotional connection remains with the other woman. It does not mean they will, but both sexes are born capable of seeing things as just described.
Women don’t seem to realize this. The more predictable she is, the less respect that a man has for her. Example: She declares loudly and often and he hears her just once, ‘if he cheats on me he is outta here, period’. She just threw up a disrespectful challenge for him to beat the odds. OTOH, if she’s quiet on the subject, she neither challenges him nor shows disrespect that he might even think about it. It is easy for him to presume that she trusts him, and he has no reason to displease her.
The quieter she is about her values, especially absolutes that reflect on him, the better she is as a wife. The more he knows that removes her mystery, the poorer she comes across as wife. The more unpredictable she remains, the greater her ability to influence him in any given situation. When men face a woman they know too well, they are unafraid to act; when they face one about whom they know little about what she really feels, they prefer not to act but at least pause to judge better what they face. The pause enables her to get her foot in the door of influencing him to get her way.
It is all a smooth and intricate game, but it is natural for her to get her way when he knows not really who she is, or what will come out of her next—as long as she never puts him down or criticizes or even claims constructive criticism. Those last things make him not care how mysterious she is about other things; she doesn’t respect him for who he is or she would not nag or criticize.
Even if he deserves criticism or nagging by his own measure, it is still unacceptable. She accepted him at conquest for who and what he is, and she is burdened to live with it. His view, at least. Her respect is more important than her love of him, so she is ill-advised to think, e.g., that constructive criticism is what he needs.
Consequently, what she will do—not what she thinks but what she will do—about the offensive things that can happen between two people is better kept to herself. The Sphinx in the home is best at getting his or her way most of the time. Unpredictability promotes marital glue; predictability about what one will do in specific events weakens marital connections.
