You raise a valid point.

I tried to control myself but couldn't and also it was intimidation.
I saw no other way. She had been unjust. She admitted the mistake "I have been blind, sorry we didn't understand each other, etc." but somehow it wasn't enough for me. I felt I deserved a bigger apology.

I was damaged and felt powerless in an unjust situation and defenceless. I displayed my "will to act if provoked" to make a point: you don't get to screw up and harm me.

I used this method reluctantly but thought it was necessary.
Clearly the consequences were undesirable for me and her alike.
Please suggest alternative ways, I would like to learn.
