Drinking is progressive. Five years ago my XABF was drinking a shot of whiskey on weekday mornings (I didn't even know he drank). I never in a million years believed it would progress to him gulping down a pint in an hour after work, and escalate into him throwing chairs when I didn't get upset enough for his tastes.
Not all alcoholics throw chairs, of course... Some are "happy drunks". But whatever kind he is, it does take a toll. You can't force him to get help (it won't work if you try), but you do need to accept that all the time he doesn't get help (for himself!) is time spent sinking deeper into the addiction.
