Well yes and no. I see your point, in wanting support from your husband, but ultimately giving up alcohol is something that you can only do for yourself. That said, if you can get support from like minded people then that will help enormously, but that doesn’t have to be your husband. Of course he can also show his support for you, and acknowledge what you’re doing without him having to stop drinking too - if he is not ready to do that himself.
Someone has already mentioned Soberdave on Instagram, he is a marvel and he can add you to a group chat where you can talk to others who have also just given up or have been sober for a while.
Lots of other stuff online/Instagram re the sober revolution, also if you’re a reader I would highly recommend Quit like a Woman by Holly Whitaker, The unexpected joy of being Sober byCatherine Gray, and Alcohol Explained by William Porter, that should get you going.
Instead of this time becoming about conflict with your husband as he’s not doing the same thing, try to embrace it as something wonderful and positive you are claiming for yourself. You’re not losing anything by giving up drinking but you are gaining so much - waking up without a hangover being only one small part. The longer you don’t drink, the more the benefits increase, both physically and mentally. Good luck to you, and would love to hear of your progress
