For me, when I chose sobriety, I was hell bent on doing whatever it took to get through each day without a drink. My spouse still drinks and that presented some challenge but I would just come here in the evenings, eat sweets, try to sleep, walk my dog - whatever I had to do to get through the day sober.
Im still green at 15 months sober but still determined.
I think commitment to recovery looks a little bit like that? Not appeasing, minimizing, blame shifting etc but quiet, grim determination (esp very early days)
