Ovrrnbw, I really believe this is great news. It doesn't mean your marriage is fixed but it seems your wife may have hit rock bottom and now she's on her way back up. It sounds like everything you've done is appropriate on your end. If you can maintain a strong stance and not let things normalize until she works hard over an extended period of time then you'll greatly increase your chance of longer-term success. I will warn you that once your spouse comes back the feelings of resentment could strengthen for a long long time. It's important to deal with resentment effectively because it could destroy the marriage a second time as was a factor in my case (among many others).
