I want to start off by saying that I am sorry you are really struggling right now. I know you don't believe this right now but life is giving you a gift right now. The best thing you can do is set aside your marriage right now and get into therapy and free yourself. If you can do that then the bonus will be that it may restore your future. Your w is not coming back to your current marriage. You simply can not use logic and reason to get her to comeback.
