dude, I'll be honest, I think a few people have touched on a much deeper issue, she should NEVER tell you that she hates you...
My opinion is drinking every once in a blue moon is not an issue, but drinking because you are depressed or as a crutch is a very bad thing. You cannot change her... she needs to want to change and as long as she doesn't see it as an issue, there is nothing you can do. Now you need to decide, do you want to live your life like this... my guess is no.
Hell, maybe if you leave her, it will be a wakeup call to her.
