It's you that's the alcoholic, correct? Are you trying to figure out why your wife hasn't gone back to behaving as if nothing ever happened, or why she doesn't seem to be working hard to repair the relationship?
I don't know what went on during your drinking days, but it generally takes quite a while for a relationship to heal. It's not just a matter of your cleaning up your act (though it's a good first step). Some relationships are damaged beyond repair. She may not have figured out yet how to relate to the "new you," or she may be trying to figure out whether she even wants to remain in the relationship.
Keep concentrating on doing the next right thing, and things will become clearer for both of you with time.
