I've been in two alcoholic marriages and am a recovering alcoholic, myself (two and a half years sober) and, yes, your husband appears to be an alcoholic. I know many people who swear they were alcoholics from the first drink. It isn't how often you drink, or how much, but how you feel about it. "In love" is a good way to put it.
I suggest you take a look at "Under the Influence," as well as AA's "Big Book" (here is an
online version), just so you have a better understanding of what it is you are dealing with.
I also strongly suggest you check out some Al-Anon meetings. It sounds like your husband has a long way to go before he will think that he needs to quit drinking (and quitting is the only viable solution for a real alcoholic), so it's essential that you get your own head screwed on straight. There is very little we can do to "help" an alcoholic, but there is a lot we can do for ourselves to minimize the impact on our lives.
