I'm SO sorry!

I had a similar experience with my T a few months ago...your experience reminds me of it. Look up projective identification. There is a thread recently posted on here about it, too. It's more than just projection but its a bit complicated so I don't feel competent enough to explain it very well.
I told my T how angry I became due to what happened (total change in demeanor) and he sincerely apologized. It took 3 months, but he finally went into a bit more detail to explain some of what he thought happened. In my situation, he got caught up in my complaint that I felt badly about myself not making enough "progress" and whatnot. It was more than that but i don't want to get into it here. But this i do know: I was never blaming him and directly said as much. It's so complicated but shouldn't be /:
