Thank you for that

You're totally right about fear... trying to narrow down the pool of things that I stress about to my own actions and what I can personally control has been the only way to stay sane, I think...
Anyway, update: she has left. Things are quiet now, there are no resentments in any direction and I am meeting her this coming week to see what we can salvage of a friendship...
I think that, once we all realized what we needed, and what was possible taking into account everyone else's needs, the decision for her to move on became pretty clear...
