Welcome to SR. Sorry to hear you are having troubles.
I was a sneaky liar when I was drinking, also. I would hide alcohol and drink it when no one was watching. I would usually have a public bottle (in plain site) and hidden bottles so I could say "Yeah, I've had a few (see, only a little bit missing from this bottle)" when in reality I was drinking quite a lot. This behavior is quite common for alcoholics.
You can't make him stop. He has to want to stop. Unfortunately that frequently comes when the negative consequences of continued drinking become intolerable to the drinker. Get yourself some support - talking with people in a similar situation can be a great comfort.
Best of Luck on this Journey.
