did she go through menopause yet or is she pre? That might be where a lot of things are coming from and there are two types of women when it comes to that "BIG CHANGE": those that embrace it and even make fun of it and those that deny it and think of it as tabu but something that they can't do much about. Sometimes hearing from you MD about the choices that can be made to make the healthstyle and lifestyle "normal" during that time might be all it takes (I would not advice you approaching her about it unless you know she would not be offended) sometimes it's like talking to an empty room.

It does seem like your W is taking a plunge - is it because it's easier that way or is it because she is not informed about the choices?
