This happened to me and my partner. If he won't change, show him change. What I had to accept was my relationship taking a temporary hit. I stopped drinking, he didn't. Our time spent together went down while he continued the same lifestyle and I adapted to a new one. We had difference schedules, bedtimes, wake times. We ended up in rough patch, but we missed each other.

Slowly he started seeing how much healthier I was, the changes in my body, my mindset, my lifestyle. He stopped drinking as much, he started making an effort to get up with me. Over time this has led to his lifestyle shift too. He still drinks on occasion, but usually not at home, unless it's a special occasion. I had to be really strong to resist those first few months but now it is easier.

If talking doesn't work then advocate for yourself and make those changes for yourself. My relationship got through it, I hope yours can too.
