MSN had an article today about emotional affairs and how to know if you are having one. Some people get into one before they realize or admit they are having an EA. Then they are hooked and don't want to get out of it. However, if your H is in a MLC, that is a double whammy.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
