That's great your going to your first meeting! I agree with ICU, you don't have to make a lifetimes worth of decisions about your relationship or your life today. Take it one day at a time. Baby steps.
If you decide to keep talking to your bf tell him the truth as you see it today. Tell him you love him because today you do. Tell him you don't know what the future will bring because today you don't know. And tell him you can't live the way it has been because it is sick and unhealthy for both of you. And yes keep telling him recovery is what he needs to decide to do for himself, for his own well being not for you. And you need to do the same for you because you have been very much affected.
Maybe after a little while into recovery, you'll be feeling stronger, and one day you'll pick up the phone and tell him you don't like being bullied by his anger and let him hang up.
