Advice... Mine would be to address the root cause. As you already mention yourself: Alcohol is a drug to cover wounds and pain, and in some dark way it's working. The price is very hefty, too hefty, and I don't want you to lose your wife and marriage.
Did you ever receive professional support or did you ever join a support group for your complex trauma? Even if it takes time to get support it's worth it. As important it is to care for the alcohol: You'll have to take on the other beast, too.
Make your wife your companion on this way and tell her you will sometimes need some advice on the right direction, or find some other companions. Don't go alone. You are not alone.
