I'm 5'4 All of my past and present male sweeties have been taller than me, most of them 5'10", the remainder 5'6", 5'7", 6'1", and 6'1". I felt more comfortable around those who were 5'10" and under -- possibly because the men in my family of origin are shorter than average so that's what I subconsciously think of as "family"?
BUT I also prefer dating someone who gives off the visual and tactile impression of being fit and physically stronger than me, though more the "mesomorph who exercises regularly" type of build than an "obsessive bodybuilder" one. The kind of person who stops at the gym for a bit on his way home from their software engineering, applied scientist, or academic researcher job, perhaps on his way home to engage in his creatively-oriented hobby.
That being said, my initial attraction to someone seems to be about 90% based on the type of intellect, creativity, and common interests they have, 10% physical. (Later on, sensory considerations (voice, cleanliness, their particular pheremones, the way they feel) can be dealbreakers). Almost all of them later (or sooner!) reveal that they have ADD like me, and some have turned out to be fellow Aspies as well. Actual job/lack of it/income have all been pretty irrelevant to me as I consider it my responsibility to provide for myself -- on the other hand, good communication, and anger management are a big deal.
My co-residential partner is quadruple-diagnosed with AS/ADD/major depression/anxiety disorder and manages to do all of the above, BTW. He is, predictably, 5'10" but even if he were extremely short of tall, it wouldn't matter to me -- he's awesome.
So... are you working to be as balanced and "together" intellectually, emotionally, creatively, and physically as you can stand to be? Stretching yourself to learn the best communication skills you can? Do you see women as potential friends rather than only as potential dating partners? Are you trying to date women based on looks alone, or do you show that you're interested in them as people as well even if they never, ever choose to date you? Do you like yourself, regardless of your success at dating, or lack of it, at given time?
IMO a lot of women WILL be put off (at least initially) by your height and neuro-atypicality, yes, but you can do a lot to attract some of the rest, as above. And you only need one if monogamous (or a few if polyamorous), right?
Best of luck... dating is an inherently frustrating process for everyone I know, Aspie or not.
