It is very difficult for people to imagine how pervasive NPD is. They tend to keep doing things with the narcissist as if she's normal. Then they get burned and they are very hurt. You are normal and have a view of personality that we call "whole". But something happened early on to her personality: it has become "fractured". What do I mean?
Let's use a parable of a house. You understand personality as being an open plan. There is the main big room where everything in the personality is and there are some smaller rooms off the main room, but they all have open doorways so that there is a unity there. If a person reacts from one of those smaller areas in her personality, it is coherent with the rest of the house, it fits into the decorating scheme of the main room, etc. It's all unified.
She isn't like that. She has different closed rooms. When she says something to you, it responds to some need and "truth" of a certain room. When she wants something else, it responds to a different room that contains that "truth". They don't have to agree for her to feel she is being okay and truthful. Because they are responding to different needs in her. Like different closed rooms.
You would not be able to feel whole that way. Well she doesn't feel whole. But she doesn't know how to feel whole. And she doesn't know what feeling whole is like.
How, then to live with her:
Step 1. You must accept that you cannot change her. This is the heart of the matter: what you see is what you are going to get for a long time (see step 2) if not for the rest of her life. Your job and your goal is to learn how to accept her the way she is and not be affected negatively by her. Yes, this is a tough, big job. But that is what she needs. You cannot be her therapist; you have to accept that this is how she deals with the world and that your job is to be there for her and with her without you getting too hurt by her personality difficulties.
Step 2. You can encourage her to seek professional help. Again, this will have to be only an encouragement. You know better than anyone that even encouraging her will probably not go over well with her, but that is the most you can do in that area. She has to be willing to go to therapy to help herself. No one else will ever be able to get her to stay in therapy and get benefit from it even if they convince him. The chances of her thinking this is a good idea are very slim.
I'm going to prescribe a couple of excellent books you can get on how to live with a narcissist. These books WILL help you as they have been tried and I've seen them have good effect if you follow the suggestions of the authors:
1. The Wizard of Oz and Other Narcissists: Coping with the One-Way Relationship by Eleanor Payson. This is a great book that will help you with the lack of self-esteem that living with a narcissist or being close with a narcissist will do to you.
2. The Object of My Affection is in My Reflection: Coping with Narcissists by Rokelle Lerner. This book is newer but is extremely clear and insightful and has helped people since it came out 3 years ago.
Okay, I wish you the very best!
