My sister is an alcoholic.
She would hide alcohol in the house, if her husband found it and got rid of it she would get more and be more secretive.
After years of physical and verbal abuse he made her leave the marital home. This was the turning point. I made her go to AA and she finally accepted she is an alcoholic. She is a lot better, but has not given up completely.
It has made her husband depressed, her son clingy and my sister and myself anxious. It is an awful addiction and I don’t understand it myself. Nothing works unless they want to get sober themselves I’m afraid.
