Hi,
Congratulations on 71 days sober! Good for you!
When you say that you are tempted to drink again, I wonder what other changes you have made in your life, besides stopping drinking? For me, I had to make a lot of changes, big changes in my life in order to begin to recover. I had to incorporate recovery into my daily life.
I suspect that your wife may be afraid of you changing. I changed when I began to recover and so my relationships changed. Your wife may have felt that she 'knew' you as you were and is afraid of who you might become. Hopefully this is something that the two of you can talk about and maybe consider counselling.
I never keep alcohol in the house, so never use it for cooking. There are plenty of substitutes like apple juice, etc. For me, I would not eat red wine sauce or something that is obviously connected with alcohol, but that's just my choice.
