I'm worried that if she does move out, you will not handle it well. You are completely consumed with how SHE's feeling and acting; what about you? What are YOU feeling? How will you live a life without her in the house? It's quite possible she's putting things in place in preparation for leaving. You cannot stop her; but you can change you. You are certainly doing better in your interactions with your wife; but are you REALLY prepared to be by yourself? You have to get yourself in a healthy position to be able to weather a separation should that happen.
