I know the natural instinct is to tell her you know about this but I say stick with the DBing and keep your mouth shut. Telling her you know about this now is likely to push her farther away and will not be helpful to you in the long run. She is most likely not in a place where she can be confronted about this. Down the road if things change this will probably be something you will want to talk to her about but right now I don't think it will do you much good. Keeping it to yourself will most likely help keep your sanity because then you will not have to hear any details about the A from her. Try not to think about this (I know much easier said then done) and focus on yourself! Good luck with whatever you decide to do!
