It is my opinion that the lack of male leadership in households is the real reason behind the massive increase in divorces.
A lot of women these days think of male leadership as sexist. "A man, lead me? Hah!" they say.
Let me tell you this, then. There is nothing better for a woman than to have a man in control of her. Women have a more emotional brain, while men have more rational brains. There, I said it. There's a difference between men and women. Ooo, kill me now. Anyway, women are more likely to do things based on these emotions, rather than based on thoughts, where men will do things based on thoughts over emotions.
God put men in the leadership role of the family. This does not mean that he is to lord over everyone in his family. It means the opposite. A man needs to put the needs of his wife and family before his own needs, even when he's mad or upset about something. He cannot be letting his emotions get him away from his true goal - to love his family as if they are more important than himself. All the time.
No relationship is ever perfect, and no man is perfect. So even when the man is given control of the family, he will still mess up.
Men have a natural need to lead their family, given to him by God. Lately, women have decided that they and their children are their own concern, and that the man is no longer needed in a leadership role. When a man does not feel he is able to lead his family, often that will lead to him becoming detached and feeling unwanted. He leaves, and then the woman wonders why there is no father. Or he doesn't leave, but there is still no father.
This isn't the only reason men leave. And it is certainly no excuse for it. But women need to figure out who needs to be leading. Encourage your man to lead the household. Support him in every way you can.
This relationship works easier when you are both submitted to God first, and then to each other. But, it seems it can work outside of that too. The key to any relationship where one party is leading is trust, communication, and putting the other first. That's the only way it can work, and it's extremely difficult to realize it.
