I would add that this personality's is highly manipulative ir the only truth they know is how something affects the narcissist at that minute ,and if her need changes , the facts are manipulated to see truth in another way .

The sad reality - This type of person is impossible to deal with and you must develop your own sense of self and close your heart to her, unfortunately . If she makes you her confidant, you will have to realize that it gives you a false sense of closeness and will soon leave you alone and in pain.

I agree because I went through all that with her.
