Welcome to a great place where you can learn a lot from other people who have experienced almost exactly what you have. You are probably still in a state of shock.
It was about 5 years into my own marriage when my wife had a seizure followed by 8 horrific days of detox and we all realized this sweet beautiful woman was afflicted, and we were sympathetic because she did seem to have a tough childhood and some kind of unexpressed pain.
But now 12 years later, it still went down the tubes. In these later years AW has taken up with other men - something I never thought would happen. When a person lies this much, it is deeply corrupting. 12 years of high drama and never ending consequences of alcoholism.
Mine is just one story. Take your time. You DO have choices. Do nice things for yourself and learn about detachment.
All the best...
