Do not leave the house. Do not leave the marital bedroom. If you work from home normally, don't stop doing that. She is the one that is wanting to leave. If thats what she wants, then she can leave. You have to detach and realize that you have NO control over her. You need to focus on YOU and YOUR issues. That is what the DB process is really about; working on YOUR issues. She will either notice and appreciate the better person you are becoming or she may not. But you don't have any control over that. Focus on you right now. Be the best James you can be.
