Corri makes a good point. General studies make general findings. But it doesn't matter if 99.9% of all men or women act a certain way, the only thing that really matters is how things are in YOUR R, and what you and your S are going to do to change things if they need changing. I can tell you from experience that the "most people do it this way" argument doesn't work very well. Each marital situation has its own unique set of nuances that must be considered.
