It will make me bitter or better!

My husband and myself are both alcoholics. I have almost 26 months sober; my husband had over 2 years till the holidays happened. He is currently drinking daily and as each day passes I feel myself backing away not speaking up. I’m just upset he is not even trying to stop. His behavior under the influence this last time, it was very scary.
What do I do?

I can imagine somewhat, my fiancé still drinks.. it usually doesn’t bother me.. he talks about quitting but doesn’t do it. I try to be supportive but sometimes I’m exhausted. I feel bad saying that but I’m sure I was exhausting when I was under the influence.
