My exhusband was PA. His big one was to ignore and grump around when he was upset about something. It didn't necessarily have to be something I did (maybe he was upset about something at work), but of course I assumed it was me (and it usually was). I would spend a lot of time asking "what's wrong," and his response was always, "Nothing." "Why are you mad?" "I'm not mad." It would eventually come out, but not for days, weeks, months, usually in a fight where I would get blamed for any number of things. The thing is, there were times I had no idea what he was talking about. Or I didn't remember enough detail about the situation to explain what happened. Meanwhile, he had several days/weeks/months to stew and brew and create his own assumptions and "reality" of the situation. How can you explain yourself when he already knows "exactly what happened" and you can't remember the thing that got him upset in the first place? How many issues could be resolved if he brought it up right away?
He would also yell something nasty or leave a nasty note and walk out the door...gone.
Bottom line, though, this was part of his abuse, which escalated when I started calling him on his behavior or not responding to it. I spent so much time worrying about what I was doing wrong and trying to fix it, as if I could read his mind, at some point you give up. So as I'm sure you guessed, the marriage ended and what a breath of fresh air, I'm still giddy not being under that weight anymore, 10 years later.

I had a boyfriend give me a gift certificate as a Christmas gift, then got mad that I didn't spend it on him.
I'm sure I can come up with more. Some of these stories are nuts!
