If your relationship with your fiancee can't survive the removal of alcohol from it, its not much of a relationship...IMO. Here's another thought. Look at how you describe your relationship with alcohol:
"our socializing revolved around friends and dining and drinking"
"Wine was a huge part of our lives"
"the center piece of our lives is now missing"
You talk about wine with more glowing terms than you do your fiancée. Could your alcoholic mind be romancing the booze a little too much? Seems like a strategy to slip out of recovery if you aren't careful.
Good luck.
