“i was told by my rav that I would have to prove that i did nothing to provoke getting beaten.”
That’s odd. I learned that one’s behavior is in one’s own hands and one cannot blame another for one’s loss of control.
Look what happens when Adam blamed Chava for his misdeed. Hashem not only punishes Adam as well, but it is seen as a ???? when blaming Chava.
Or when Shaul blamed the people for his misdeed…he lost his kingship.
Hard to imagine a rav doesn’t know hashkafa that we are responsible for our own behavior.
Perhaps ask another rav. And get help.
Hope at least the physical effects of the beating have gone away, but the emotional and psychological effects tend to take lots more time from which to heal.
