At this point I would just be making accusations about the A. I have no real proof to present to her. Just some texts I've seen and her behavior.
I want more than anything at this point, other than repairing the family, is to call her out on the A. If I do call her out right now she will just deny it and hide it even more.
If I could get her to admit it, that would be another story. She is a smart cookie, so tricking her in to it would be no easy task.
