Val, I admit to a bit of projecting here so take this with a grain of salt.
Less is more in this case. All you need communicate is “Just the facts”. The excess seems conciliatory to me, and I perceive a weak image projected. I have not gotten the sense she has softened with conciliatory gestures. The concern here is if weakness is perceived will she probe for more?
I do not think you owe her. I think you owe yourself. Do what you believe to be right and represents who you wish to be.
