You'll get more, and better advice, soon from others. But I'll throw in my .02 cents now:
It's not your fault
It's not your fault
It's not your fault
They lie, the blameshift, they guilt.
Stop counting his beers - it won't do you a bit of good. Don't yell at him, it will do no good and he doesn't care what you think.
Oh, and it is a "really big deal" if you are so upset.
Peace to you.
