If you remain silent, you are telling her that you either approve of what she did, or are afraid to confront her or that it doesn't matter to you. It will also allow her to do this to someone else. By standing up to her you will hopefully save someone else from this situation, as well as get your situation handled. It shouldn't matter who she is or what position she holds. You were cheated and if you let it go, you will be hurting yourself as well as letting her continue to be dishonest. We're pulling for you. As Red
Green says,"we're all in this together." Let us know how you do.
