R2C is right about the arguing. Stop arguing, and start listening like you were talking to an unattached friendly cashier at the store. You know. The kind of interaction that has little impact on your emotions.

Wolf I am going to play devils advocate here. If you changed everything about yourself that W complained about in 24hrs, and made it stick. Would it make a difference? Its too late anyway. Right? For her and the marriage anyway. There is free will and free choice. People do because they want to do. Name one or two things W has validated about your experiences about the M positive or negative lately. Name something, anything nice, selfless, or caring or considerate your W has done for you recently. Name one kind deed your W has done, or has acted compassionately about, or accountable for for the downfall of the M. Don't you see? She is not your W any longer. She is not the person you married. This is all about her right now. So only when and if she brings things up. Keep it about her. If she wanted back in tomorrow. Would you take her back without her showing you some kind of proof or change on her part? Futhermore? Why would you want all this drama in your life. Another thing I realised as of lately. Alpha males never complain. They just do. They just handle, they just are. They are not riddled with emotion because they are too busy living for themselves, regardless of who is in and out of your life. You are the prize. Remember that. You come first. After your kids. I know it's easy to get attached to memories, but you need to save yourself. I finally came to the realization that I wouldn't take anyone back that would want to leave me get away from me and not want to be with me. That they would be the ones that decided to leave and that's their choice to do so. That most likely there will be only two reasons for them to come back either their first option plan A didn't work out for them. or that they had a considerably serious change of heart and they would have to demonstrate over time with more than just words, but actions. Be done with it and get on with your life for you. Maybe she will come around one day and maybe she won't but I wouldn't wait or expect it.
