TWO WEEKS?
It's not like an alcoholic puts the bottle down and everything is fine. It takes a loooooong time to change, it's a great deal of hard work. And some people don't change, don't stay sober. While it's wonderful you support her sobriety, there's nothing you can say or do that will change her.
But is this what you want for your life? I think that's what you should ask yourself. I don't know you but I'm 100% certain you deserve better than this.
