Sannah,
I am intrigued by reading your post and all the responses. I also think I had a mother who was, at the very least, marginally Narcissistic. In my adult life, I have been drawn to relationships with Narcissistic men.
In my research, in moving toward being more self-caring, I have realized, first, that I was not raised to have my own voice, to express any emotion, and certainly not to have any of my own needs fulfilled or validated while growing up. I was punished for attempting to do such a thing.
As a young women and thereafter, I have found myself in relationships in which I was doing all the accommodating, all the caregiving, all the encouraging, while receiving nothing in return...since this felt comfortable and familiar.
Researching the Narcissist, later in life, I realized what I had been drawn toward in these relationshlps. I now hate the fact that I had so little self-worth that I felt I didn't deserve a reciprocally loving relaitobnship. But I finally learned what was wrong with my thinking.

Not to be too negative here, but for the true Narcissist, I think there is no improvement or change. That is what all the literature says as well.
