Hi bobbysocks, and welcome. It's normal for the A to get angry when we start to set boundaries for ourselves. I was taught that it's okay for my ABF to have his reaction to my boundaries.....it doesn't mean I have to change my plan.
One of the first things we learn in AlAnon is the "3 C's". We didn't Cause the alcoholism, we can't Cure it, and we can't Control it. The only thing we have control over is our own life and future. Your AH has the right to drink if that's his choice, and you have the right to decide you won't live with an A.
There are great sticky's at the top of this page. "The Language of Letting Go" and "CoDependent No More" by Melody Beattie are great books. Find an AlAnon meeting near you, there is tremendous support in those rooms. Take care of you.
