You have good days and you have bad. That's why we called it a roller coaster. Eventually you will have more good days then bad and then the majority will be good days.
The problem you are having is that you are a male and are thinking with logic and reason. You think because you are going to MC you are working on the marriage but in reality you are not. You think if you can talk about it you can use logic and reason to convince her that staying married is the right thing to do. As a woman, right now she is making decisions based on emotion. There is a saying around here. When she is working on the marriage you will know until then you will be confused.
