Oh..hard answer to try and give here. Think I would phone the police and turn him in.
Haven't had this problem. Guess I'm lucky in one way...my AH doesn't drive while he is drinking. He was arrested once..many years ago..for drink driving. Hopefully he learned his lesson. But if he did decide to drive after drinking..I would phone the police. Thats just me. I would feel so guilty,if he would cause an accident and kill some one.
Know this is difficult for you,but you aren't alone. Know other people here have had problems with this.
I hate being married to a AH. The stress alone is overwhelming. If I stay in this much longer I will be completely grey headed!! I am back to bitting my fingernails. May start on my toenails soon!!
