No matter what his excuse is, there is no reason whatsoever that he be nasty with you. He could be grumpy because he hasn't been able to drink the way he wants to, he also could have snuck far more to drink than you realize. My AXH was a pro at deceptive drinking. Either way, his moods are HIS to own, it s not your burden... no matter how much he tries to convince you otherwise.
My AXH ruined several anniversary "celebrations". I'm sorry this is happening to you too.
