My partner wanted to "talk" to me after a night of total crazy out-of-control drunkenness. I was already ashamed of myself and never wanted to talk about "it". I liked the idea of just avoiding it and ignoring it but of course, continuing to drink.
One time she was trying to talk to me about it and I said "I know what you want me to say and I'm not quitting drinking." I eventually figured it out for myself.......quit some time after that "talk". Your GF is going to have to decide for herself what she wants to do. Sounds to me like she doesn't want to quit right now.
Going to alanon is a great idea. You need to take care of you because you can't control what she does.
Welcome to SR. Glad you're here.
hugs.
