Good morning DJsoon.
I have a female friend who also drinks like a fish, it got so bad that her husband left her but stayed in touch to help raise their 4 girls.
Long story short she eventually met and married a man who also drinks but can control it and as a result she drinks less, they both work hard and play hard and they are both good friends of my wife and I too.
The former husband also met and married somebody new and is also happy these days.
Alcohol is such a toxic substance and I had to stop because it would have probably killed me, now I’m only addicted to opiates and have been dry for about 13/14 years and have a much better life and strangely the opiates helped me to stop.
There are so many different types of drinkers but the worst are the aggressive ones, when drunk the worst thing that I did was to telephone my lady friends and in the pubs and at parties I was the life and soul of the moment (I thought) but in the end my wife said she would leave me so I eventually stopped completely.
To quit the booze I had to move from the town where I lived and moved to the countryside where there were no pubs or clubs and therefore fewer temptations.
In your wife’s case perhaps medicinal cannabis would work, it does for some and is better that drinking thats for sure but she obviously isn’t happy with you for some unknown reason perhaps you can both sit down and write what you like and dislike about her and she does the same about you.
All the best.
