That completely blows Florence.
It sounds like she's become a completely different person from the one that supported you during all of that chaos. This reminds of when RAH got lost in his addiction & he surrounded himself with even lower-functioning people to make himself feel & seem "better than". There was definitely an element of like-draws-like happening there.
I know how badly it hurts to feel betrayed like this - even if it's not personal & all about her being lost in her own issues, it still hurts. I'm sorry you're dealing with all of this, but SO happy to hear all of the rest of your wonderful updates!!!! ((((Hugs))))))
