Hi Speedy - first, kudos for not drinking since Saturday. Part of recovery is living life on life's terms and not running back to the bottle or the drug when stressful and upsetting things happen. Don't be too hard on yourself - you made a mistake, but take a lesson from it that you can apply in the future. Fights with loved ones can be triggers - what will you do differently in the future? People say all kinds of mean things in the midst of an argument - if you and your wife have kissed and made up then I'd let it go and move on - it's a new day with all kinds of possibilities!
Hugs!
