A colleague of mine is responsible for one department and I am responsible for another. She has the boss' ear and constantly takes over my projects. I have spoken with her about it and she keeps doing the same thing. She needs to feel like she does everything and presents herself as the go to person. When I bring something to our boss to review I am told to ask this person what she thinks. Normally I would take this personally and be very worried about how I am being perceived, but I realized she is not going to change, the boss is not going to change, so why fight it. Let her keep thinking she is controlling everything while I just do my job. Sad when women are "frenemies" instead of lifting each other up.
