NO!
You are not wrong in feeling that way. It's clear he simply doesn't understand how hard it is for an alcoholic to be around drinking... especially at 12 days. How can he understand it if he only drinks 3 beers a year? To him, it's a no-brainer.
He can no more understand what it is like to be an alcoholic than he could understand what it is like to have a baby. You can tell him... but unless he's actually experienced it he simply won't "get" it.
**{hugs}} You are most certainly not unreasonable.
