This is a very tough thing to get through. It might be a good thing that your wife moves out because then she can feel safe and might begin to miss you. She might be better able to see your changes from a distance.
Focus on you, detach from her. Most importantly, work on yourself.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
