My sister is an alcoholic. She used to drink all day, every day. Like I would drink cups of tea.
If she decided to top up the eighteen cans with whisky or worse raki that’s where the trouble would start. She was pure evil with her tongue the things she would say were so hurtful. This was to me, my other sister and her own husband. She would turn on friends too. Afterward she would have no recollection of what she had said or done and would be mortified when confronted. I have mental and physical scars.
If your other half binge drinks on occasion this could be sorted if she loves you and doesn’t want to hurt you just by cutting down, so the episodes don’t happen. Easily said though. She can only do this herself no one can help if she doesn’t want or feel the need of it.
