It may be her way of reminding you that she is not the only "bad guy" in this M, and it's her way of taking some of the heat off of her own A.

Did she tell your parents or anybody else about your A? I'm thinking that she still feels the "fallout" of the exposure of her & OM.

It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
