Of course he can't understand because he is not an addict. My husband is the same way. He thinks people can just quit. He is being kind of an idiot and he can't do that right now because you need to get some time in before you are strong enough for that kind of trigger.
This had bothered you before so I would make him understand this is very hard for you. It should be no big deal for him to just quit wine or a year or two. He still gets his beer after all.
