We all pretty much learned after a hard way, by finally going to Al-Anon, that we didn't Cause the alcoholism, and that we can't Control it or Cure it.
You are in a physically and emotionally abusive and violent setting. Please give serious consideration to a battered women's shelter. Many of the hot buttons that seem to accompany domestic violence and abuse are present.
Then get to at least six Al-Anon meetings, in different groups, soon.
Take care of You. No more sitting on the sidelines, watching as it were.
