Ok, just to throw an idea out there...and, I could be completely talking about myself just as much in the situation you described, but...
what if, it was *you* thinking he was blaming you for his bad decisions and really, he was just frustrated at himself---and then kind of being a jerk about it?
We, alcoholics and not, make stupid mistakes all the time, and there is NO reason or explanation for it. And most of us are our own worst critics.
What if, perhaps, he was just plain mad, and not 'mad at you'?
I truly have detached to the point that something like this would just pass right by me. Maybe a "Gosh, that didn't quite happen with the greatest result, but hey, stuff happens." ...
Analyzing everything has gotten me into lots of trouble with this kind of thing. I do not internalize these type situations anymore.
Is that something that resonates with you at all?
