Did this girl have a disorder such as npd/hpd?

Hi,
New to the board and stumbled across it whilst trying to reassure myself I was sane after a brief experience with a girl I was seeing recently.
I will try and include all the info whilst keeping it short as possible, I guess I just want affirmation that there was nothing I could have done to alter the outcome. (this took place over the space of 2.5 weeks)

Right, Im a 35 year old guy, class myself as decent looking, intelligent and kindhearted.. Whilst on a night out locally back in mid january I saw a girl I used to know who introduced me to one of her friends..she seemed very outgoing bordering on outrageous, doing things like flashing her underwear to all and sundry whilst in pubs etc for a reaction.
Now normally this thing puts me off but as she was a pretty girl (23 years old) and the fact that she came talking to me then asked me for my number and took photos of us out in the pub together I decided to send her a text.
She seemed keen to meet up so I went to a local pub where I got to know her a bit, she lived on a local estate with her mother and her mothers boyfriend, didnt have a great education but seemed very socially switched on! Has a 2 year old daughter to some guy that she told me had treated her badly and held a knife to her etc so she left him. Doesnt know who her father is and doesnt want to.
She was very nervous and told me so which I found endearing, she carried on by telling me that she worked part time in a local pub and liked going out a lot (6 nights a week - coming in at 5,6,7am!) as there was nothing else to do...?
We talked and she had her phone with her constantly receiving and sending texts to people while we sat and talked... which was strange but she apologised and said she knew it was bad but couldnt help it.
Anyways I took her home later and dropped her off at hers, I took off my seatbelt with engine running to give her a kiss and she asked "why are you taking off your seatbelt" in a flat tone? I felt a bit weird but told her and she was ok with it.. Found it a bit strange. Asked to meet me again which I said ok to against better judgement.
(must add while in the pub she insisted on paying her round)
Met up a few more times with her and she opened up telling me that she didnt really bond with her little girl (i.e not really bothered about her) never really got bothered over men but always had plenty willing to take her out and as long as they were half decent looking she was up for it). didnt have any aspirations or dreams or anything, but insisted she was very happy living in a shabby house and drinking every night.(even if she won the lottery nothing would change)
Now I may sound like im mad but I wanted to help her and show her what life can offer(white knight syndrome?)so we arranged a night away at a nice hotel (she had been texting me constantly telling me how she really liked me and I was gorgeous etc, cant wait to spend time with you and so forth up to 50 texts a day)
Anyways we get to the hotel and she starts saying you want to get me into bed don't you and you're trying to have sex with me..half joking half not. Now dont get me wrong Im a guy and yes if she wanted then Id be more than happy to sleep with her but I dont do stuff like just dating a girl for sex.
We went out and had a great night then got back to the hotel where she put on her pyjamas and turned over and went to sleep without hardly a word after kissing me and generally getting in the mood for something.. Frustrating but never mind I can wait so i thought.
I asked her in the morning if she had issues with sex as this "you only want me for one thing had come up many times" and she responded almost semi sneeringly "I have such a high sex drive that you wouldnt be able to keep up" "Im always wanting it"? Found it really odd as my experience with her was to the contrary.
Dropped her off home and she changed tack again to nice girl and said "I really enjoyed it and I really like you"
So we carried on as usual on texting again to fix up a new meet, I arranged to see her the next day but when the day came I never received a reply to my text.. called her - no reply. Went round to her house but she sent a friend to the door who said she cant see you at the minute but she will call wou back in 10 mins. Needless to say the call never came. Sent her a facebook message the day after asking what was wrong but never replied??? Bizarre..

So to reiterate...went head over heels for me in a few days...wanted to see me all the time.....came home at all hours when I asked what she'd been doing til 7am every morning there was always a party at someones house - usually a gay friend so im told!!!...Strange lack of emotion over anything in her life (apart from me at the time)....Cut me dead in the weirdest way after being full on and refused me any closure (happened instantly after I told her that I really liked her too)

Now I only saw her for a short time and I dont know why it bothered me so much but I ended up a bit depressed for a few weeks and am still sort of getting over it (I felt bowled along my the intensity of her attention at times i suppose)

So my question is although I have dated plenty of girls and some of them had quirks or were fiery and 1 or 2 were cheaters I have never felt anything like the reaction I had to this girl or been hooked in then shut off dead from someones world.. In truth I could see at the time that we wouldnt have worked but something about her made me want to try and be the one that broke through what I thought was her barrier.(now looking back I think it was alot more sinister - staying out all night every night...calls from men on phone but she always said it was some idiot that she knew and rejected the calls...very plausible...acted almost frigid in my company but claimed to have been with quite a lot of blokes)

Any answers?? I know I'm a fool but If anyone can explain to me then you people can.

Bump. If this is in the wrong forum can moderators please move?
