Is this PD or ASD?

Hi,

I am new to the board. I went through a rough 6 months trying to figure out a girl I have been dating. Now that things have ended - quite abruptly, I do want to know whether I have been dating someone who is different from the average Joe out there. I do note though, I never thought or treated her like someone with an issue. I just thought she was an extreme introvert and read articles to tackle with introverted people.

A little background info is that she's introverted, conservative and traditional (Asian).

People's opinion of her (from both guys who dated her and some girls who've seen her): self centered, cold, lots of pride, isolated, weird, boring.

My observations of her after 4 months of seeing each other:
- Doesn't talk (mechanical or very short answers)
- She appears to have limited facial emotions although I thought that was just part of her manners to not reveal too much
- Not much body language
- Others have commented she doesn't dress her age or dresses weirdly. She's 31 and puts on a Mickey Mouse hoodie, hot pants and leggings when it's still snowing outside (I dont know much about female fashion and thought it was cute at the time, but other females commented on it)
- Gets very uptight when talking about her past relations (I know she's never had a steady relationship before, and she's been dating different people for a few years now, but I wanted this info to come directly from her)
- Can talk only when I hit particular topics, or if she's in a certain environment (e.g. NBA playoff game) or sees a certain object - then she would ask a lot of questions and become active
- Poor sense of humor, I try to crack jokes but she'd be like...'what's so funny about that? It's stupid'
- Curls her hair and sniffs it fairly often
- Seems very rigid - insists on walking on pavement to go to my car instead of hopping off a 0.5M grass embankment, must schedule dates 1-3 days in advanced
- Extremely protective of herself - thinks biking is too dangerous, will not jay walk on a small 2 lane road with traffic that are 10-15 seconds away from us; one time there was a dog that came out of the water and wanted to play with her, she got scared and hid behind me. She then told me she doesnt dislike dogs but she was afraid to get her dress wet. She looked really nervous and made sounds that indicated fear as the dog tried to get near her while I blocked it. (Maybe she is only OK in a controlled environment?)
- Does not have a lot of friends, maybe 3-4 she hangs out with often but they're all from workplace (one of which is very close)
- Likes solitary activities - swimming, running, painting, movies, reading (fantasy/psychology books), traveling (solo or with that one close friend from her workplace), and at most, card games.
- Somehow when I touched her lightly on the shoulders with both hands from behind to steer her in the right direction while walking to a basketball game, she told me not to push her (I hardly applied any force)...but then again she would, at the same time, let me read her palms
- Likes to eat the same type of food - sushi, wings and burgers (and same flavor etc)
- Eats slow but eats a lot...she's skinny but yet eats WAY more than another guy I know who has a huge appetite
- Queries about my job to a point it gets so technical I don't know what's the point in her knowing more
- Extremely smart, or at least, book smart (lots of designations, one of which I have)
- Must text. Refuses to use or pick up phone. Even if it means Moon is crashing into Earth
- Is drained of energy after a day out (no matter if it's dating or work) and usually have to stay home the next day
- I think she's also a little...suspicious of others or have trust issues. After 4 months of getting to know me she still tells me she is not very clear about my background and personality
- Some weird observations: 1. Obvious strands of white hair was showing and she didn't bother with it; 2. when I showed up to her place unannounced to check up on her, she came out with really dirty glasses; 3. One time I saw 2-3 strands of very obvious leg hairs on her legs...but the rest of her legs were clean.
- Isolated - she would excuse herself from a dinner table full of people to fall asleep or play with her hair/phone; or when people are outside a cottage chatting, she would be the only one inside the cottage until someone drags her out
- Low energy level - must be home by 10pm. One time during a dinner date she literally fell asleep on the couch. It was like 9:45pm only.
- She's 31 but looks as if she's 25. When something excites her she acts like a 15-16 yr old
- Very unwilling to try new things unless deemed 'safe' (won't bike, as its too dangerous but dont mind sky diving!?)
- Takes selfies in environment she likes and was proactive in asking me to take pictures together...and solo pics of me (I didnt respond well as I dont know if I should touch her while taking pics since she's so sensitive and conservative)
- She broke off relations after I threw a fit at her - the trigger was my fault but the underlying reasons was just the lack of communication in general and since I assume she's just like any "NT", I got upset.
Initially she apologized but as I cascaded and got emo she then switched and said she cant develop further feelings for me after so many months; and when I asked her whether she it was her wish not to meet again, she paused and replied yes. ALL THIS WAS DONE THROUGH TEXT (while I used voice recording and it contributed to me being edgy since she refuses to talk on the phone - there were so many miscomm. just by texting and I know I don't blow up when I can hear her tone). But before this all happened....we were scheduled to date on the day before her birthday and spend a little time on her actual bday.

*Her dad, after we cut our relations and when I made a visit to her place, asked me whether I have a lot of friends. Also asked me whether I go to a lot of social gatherings...which I found weird.
*Her mom and dad looks introverted.

I am personally an introvert by default but have been trained since 6 (in very cruel ways lol) to socialize. I also have other extremely introverted friends who share some traits I listed above but all of them thinks the signal she gave, the aggregate of what I have observed and degree of severeness of each of those traits cannot be explained by a simple extro/introversion spectrum.

What do you all think? I can't really figure out whether she's a schizoid or AS or paranoid or social anxiety or something else. Schizoids I would think won't bother with trying to meet people on dating websites (she's looking to get into a relationship and to get married - she's quite old for someone of her cultural background and her parents are worried for her).

I'm over it already but it would be nice to have a proper explanation for her behaviours.
