I’ll assume the 50/50 split was a conceptual one; that it’s a bit of this and that, rather than a strict 50/50. Otherwise, I’d go with “I don’t know”.
I tend to live in my head; I am happiest there. I conquer my inner demons frequently and I’m at peace, most of the time.
But external situations cause me grief and suffering. Is it caused by them or by my response?
Well that’s the thing: BOTH.
To me, culpability [of any sort] is _always_ a shared phenomenon. The differences between the culpable parties is a matter of degrees, some culpability might barely be there at all… but still there nonetheless.
