No. They're both her, and she is both of those people. Neither is 'her real self' in the way you seem to mean.
First, some background. There is an approach to psychology called Transactional Analysis (look up Games People Play, by Eric Berne, for more on this). The basic concept is that each of us has three 'ego states', three different ways of interacting with the world and each other, that between them make up our personality. These ego states are Parent, Child, and Adult. At any given time, we're in one of these ego states and we can instantly switch between them. The Child ego state is impulsive, hedonistic, sometimes loving and sometimes rebellious. The Parent ego state is controlling or loving, and is responsible for discipline and for self-comforting. The Adult ego state is rational, dispassionate, and analytical.
This is just from my experience, but I believe that in HPD, the development of the Adult ego state is impaired, and if she can take on an Adult ego state at all, it is with difficulty. My guess is that her lack of a close bond with her mother forced her to overdevelop her Parent ego state, which which interfered with the proper development of her Adult state. In her Child state, she acts impulsively without real thought for consequences, she can be rebellious, tell lies to get out of trouble the way a small child would, tell tall stories for attention, etc. In her Parent state, she can either be caring and nurturing or she can be bossy and controlling, and she treats others as if they're incompetent children. This is where you get your "two different personalities".
Edit: Thinking more about your description of the early days in the relationship:
The woman I met two years ago the was flirtaceous, seductive, charming, quickly got me in bed...moved in immediately...talked in a chld-like voice at times, discrete control freak like organizing my closet, replaced some of my wall prints with hers etc
This stuff all sounds like her trying to make herself feel more secure in the relationship. She was making it her place as well as yours.
This all changed two months ago when I continued to not commit to her...ie support her....and she finally got a job. Now she is this super control freak in business suits, always on the phone, "I'm in charge" attitude.
Not sure what you mean by "not commit to her" - I'm assuming you mean you didn't start supporting her financially, rather than that you refused to commit to her in terms of an exclusive relationship? Either way, when she got a job she had to take on her Parent persona more because it was the best she could do to cope. She probably felt way out of her depth.
I can't explain why but I would stay on the other side of the house, I think because her super-control freak personality was so abrasive to me. But by 9 pm the little girl emerged and she would be curled up on the side of the bed in a tiny ball, refusing to get near me.
When you avoided her, she felt abandoned and would either stay more in her Parent persona (probably trying to comfort herself as much as to deal with the uncertainty and fear of abandonment), or would just collapse into being a scared little girl who doesn't know how to handle it.
On one of the last nights I turned on the bedside light on my side of the bed and she looked over and in a 5 year olds voice said "What are you going to do....kill me?" I said "what?" Then she went back to sleep.
Could have been a bad dream, especially given what she was going through.
