This *is* going down a dark path.
No more than 10 sober days since the new year? That is obviously a problem for you, and I don't blame you. I wouldn't want a partner for whom it is so difficult to be emotionally present either.
But it doesn't seem to be a problem for her, and there's the issue. Your love won't make her sober. She has stated that you having a problem with how much she drinks is something you just have to live with. She doesn't get to decide what you can live with.
We don't always get happily ever after with people we love. Sometimes we're ready for that at a time when someone else isn't, and it sounds like your girlfriend has a very long way to go. The only question is how long are you willing to wait for her to catch up?
You deserve a present partner who can deal with life on life's terms. I can't say whether or not she will ever move past this, but she has made it clear that right now, it isn't even her intent to.
