The work to build hope to repair the marriage is done inside of you. You're resisting and believe me, I understand why. It's uncomfortable to look at your marriage from her perspective, to look closely at your faults, to admit to yourself and others where you fell short. None of this is to say that SHE doesn't have faults but that's not the focus right now. You don't want a divorce. The way for THAT to maybe happen is to first recognize your role in the demise of your marriage. She wasn't getting what she needed because she left. What does she need from you? Chances are she asked for it lots of times.
