This is significant drinking. Alcoholism.
I don't know how much you have looked into CODA but I think it would be helpful to you.
In one group I attended, I read and worked through the original AA Blue Book with a sponsor. My first thought was- what does this have to do with me? Alcohol isn't my own issue, but the insight to the addiction aspect and enabling/codependency was helpful.
Published in 1939, the language reflects the culture of the times. In the book, the men were the alcoholics, the women were their wives. We know now that it can be either gender. The original authors, men, were Christians so there is a spiritual aspect to it but the program is universal, adaptable to any belief system.
The alcoholic men in the book seemed to have loving caring wives. The authors found they could help the alcoholics recover but then somehow the men would go back to the wives and get worse. Why? The wives were loving and caring- how could that be? The wives wanted their husbands to be well and weren't intentionally doing this. The authors then discovered the enabling aspect of the partner, and wrote a chapter for "the wives" and CODA evolved from that.
While it's clear that your wife has a drinking problem, that it's gone on this long in your marriage also involves you. We have no control over someone else's drinking. An aspect of the program is looking at our own enabling behavior. It's not always obvious, it looks like being caring and helpful. It was not comfortable to have a sponsor turn the mirror on me but it was very helpful and I think it would help anyone in a family relationship with an alcoholic. It may be the "wives" in the book but all family members are potentially enabling. Your daughter may be interested in ACA at some point- which became the best fit group for me, after trying both CODA and ACA but the information I learned in either one was good to know.
Even if you do divorce- the information is helpful and also, a sponsor would be a support person for you through the process. It's a lay group, doesn't replace a therapist or lawyer, but helpful in addition to them.
