Any guy who never even sees it coming is too clueless to live.
I disagree. Women are very adept at long term planning, secrecy and manipulation. Have you ever noticed that it is usually the man who immediately moves out of the family home even though it is the woman who usually initiates the eventual family breakup? The women know they have the power of the law and the courts behind them. Even if they don't know how powerful the State's backing can be, the first lawyer they see will gleefully explain it to them.
Women hold all the cards in this type of situation. They know that eventually they will gain control of the children and will have access to whatever family assets and/or income they will need to maintain their customary lifestyle.
Not at all. When I was in college, I worked at a concrete plant to help with my bills. A guy who I worked with had the exact same thing happen to him. He worked full time (and it was HARD work) and also on the weekends. One day he came home to find out all his furniture was gone. He even has to pay alimony now. Thankfully, he is remarried to a nurse who makes more than he does.
Actually I've always heard that it's pretty common for one spouse to think they have a happy marriage,while the other is considering leaving, divorce, whatever. Think about all the affairs that come as a complete surprise.
