I told her my boundry that will keep us together is for her to tell me sooner that she had that first drink, not lie about it even though we all know what's happening, and get her help BEFORE we are at the detox stage. She can't commit to it.
Do I and can I keep waiting?
It sounds as if she has given you her answer to the boundary you set. It sounds like she is letting you know she can't respect your boundary because her commitment lies elsewhere; namely, with her drinking.
It's a tragic situation. I think you have the answer to your question. As to whether or not you can keep waiting, that is up to you. I think she has made herself pretty clear on where she stands.
