Welcome to SR, thetroubledone.
I was a binge drinker. Not in the mornings, not every day, could go weeks or months without sometimes. But when I started, I didn't stop. I'm an alcoholic.
If alcoholism is not treated it will get worse.
When it started causing too many problems, I said I'd quit and I really meant it at the time, but the addiction was stronger than my resolve and sooner or later I'd start again.There was nothing anyone could really do to stop me until my drinking hurt me bad enough that I couldn't take it anymore and got help for myself.
This is a good place for you to educate yourself and get support. She likely won't stop until she hurts enough. In the meantime, learn how to take care of yourself.
