Honestly, it doesn't sound like your husband is an alcoholic. However, I am only hearing one side of the story over the internet. Plus, alcoholics lie and hide their drinking.
Either way, there is a problem that needs to be addressed and sounds like that problem runs deeper than figuring out if your husband is an alcoholic or not. Plus, it may be better to look how to fix this problem before you fully understand it. Sometimes action precedes understanding.
I am in no position to give advice on how to handle your situation besides questioning if your focus is in the correct direction during these confusing times.
Bests,
