I'm so sorry sva. I had something similar happen to me in my past and while you are 100 percent right in saying that it will never be the same again, I don't think that means you cannot share a future together. Maybe a better future and maybe "same" was never that good anyway.
I would give it a week and then start a multi-part conversation with your wife about what she wants and what you want, etc. If she has already moved on and wants out, that will save you a lot of suffering potentially.
AMAZING that you didn't drink. Nearly three years sober. Wow, just wow. A graphic and moving show of strength on your part. You can get through this.
After my experience I drank for several more years, so don't do that. Living in Day 75 here and hoping I can learn from you when it's my turn to walk the gauntlet.
