Have been away from this site for a while. Very concerned at what I've been reading.
Agree with other posters, you and your children need support. The only person who can make your wife get help is herself.
The comments about alcoholics have been interesting. I have a family member who cannot hold her drink. Every time I visited their house, she had a glass in her hand. One time, when bragging about her weight loss, she said "I'm going to WW so I can drink more". She never appears drunk, just aggressive and rude. Yet she holds down a full-time job.
I cannot add anything new to the comments already made. All I can do is hope you and your children can move on positively
