Sounds like your wife might want to learn a bit more about alcoholism.. That being said, however, your sobriety or lack thereof is not her job or business to attend to. If I kept drinking whenever anyone told me it was 'okay' to, I'd be just as drunk and worse than my last rondezvous with the detox center. I wasn't able to stay quit, until I truly wanted it for myself. I hope you get there sometime too
Welcome back from your trip.
