Marriage/relationship: Women initiate divorce on a good man

Why men seek loyalty in a woman, we live in an age where woman will initiate divorce with a good man who has sacrificed for her and for his family. She will even admit that he's a good guy, but she's just unhappy, she's bored, she's hit a midlife crisis. Her hormones are out of whack. But what's messed up is that she just wants to be rid of the guy that she views as in her way of the excitement and change that she wants. But the difference is is that a loyal woman will continue to value the qualities of a good man through her own unhappiness, her boredom, her midlife crisis and her hormonal changes. She will not make a permanent decision based on what she knows is temporary feelings and that is exactly what a good man needs.
