I'm happy for you. To everybody else I say, for the love of God please don't use this post as an excuse or rationale for making incredibly horrible decisions related to your situation with your alcoholic. Each situation is different, and this may in fact work out for her.
My biggest fear is that somebody reading this, who has clearly demonstrated that the only reason they are on this board is to find support for their bad decisions past, present, and future, and has demonstrated zero introspection relative to their part in it, will latch on to this as their rational to hold on while being dragged through hell when all they have to do to save themselves is let go.
When God gives you 100 reasons to leave, and only one reason to stay, why is it that people only hear the one reason and not the 100?
Take what you want and leave the rest.
