I don't know the path of recovery you're taking, but you and your wife might both benefit from reading about alcoholism. The AA Big Book comes to mind. I've also seen a lot of people here on SR recommend Under the Influence. I'm not saying reading will cure her anger at you, but she might better understand why you acted as you did. Sometimes understanding is part of the puzzle you have to put together to let your anger go.
Besides that, it's not mentally healthy or healing for her to sit around all day re-hashing old hurts and wrongs. It just keeps the wounds open and festering. She may be looking for a way to move on without even knowing it. (And I could be totally wrong)
As for you, perhaps you could do your best to show you're making a change. (Not that you're not already doing it.) Do the things you didn't feel like doing for her when you were drunk. Don't argue with her when she's angry. Anger is a luxury you can't afford so early in your recovery.
And I hope something in there helps.
