Kate,
You are one of the most beloved posters on this site. I'm saying this because what I'm about to say might sting a bit. My amateur psychological evaluation, and that is all that it is, is that your 'reasons' for going back to the KH have nothing to do with this sister. Nothing.
We've all read your emotional struggles to find justice with the KH and its elders for the unjust way you were treated. Most of us have been there, and we deeply care, understand and feel your pain.
I believe that is the sole reason you are considering going back to the KH. And I believe by asking you are trying to get us to talk you out of it. The more we rationalize the less rational we are.
So to answer the question you posed: No, not in 1 billion years would I ever return to a KH given the scenario you described.
Good luck Dear Kate.
Hi Kate, I have never posted to/with you before so I wouldn't presume to post what those who know you would. I'll just agree with them!😃
