It's going to keep happening until SHE decides that she cannot LIVE like this any longer ... that the pain of drinking and its consequences (on HER) is worse than the pain of not drinking.
Please consider going to Al-Anon meetings as soon as you can. Those are for YOU and how to cope and recover yourself. Read the stickied threads here too. Learn about acceptance, boundaries, changing what you can, codependency, detachment with love, letting go, living and letting live, and serenity.
May serenity be with you in this long ordeal.
