I think i agree with hope, as in i wouldnt push for her side of the story. But if she ever brought that up again and wanted to tell you then i would listen and validate.
Would it make any difference? What if she told you her side of the story? Will you life or how you feel change at all?
I would either leave it at that, or respond with something neutral like that must have been uncomfortable for you, i understand. Hopefully things will settle with time.
