Not sure if this helps, but...from the other side...where I'm basically a NT liking an autistic girl...it might be a perception issue on their part. I don't know how to say this nicely
but...i grew up running from anything to do with anything mental at all(right after the people who hate autistic people diagnosed me with autism). I grew up as an NT... I learned from everyone around me, that autism was grouped in with all mental disorders. And that there is "something wrong" with all people with them.
Just having people know you have ever seen a psychologist or something is enough to get you shunned sometimes...
and reasons why a beautiful kind autistic girl might have trouble with someone dating her are I think:
"ok so what's wrong with her exactly?" Even though I'm attracted to her, I have to ask "is she even mentally capable of making the descision to like me?What if she says she is and I believe her but then, her family has me thrown in jail because she WASNT capable of consent?"
As far as the dating part...her brother would kill anyone making a move on her. They trust nobodies intentions and all the people around her think that she can't take care of herself so that dating her would be "taking advantage" and everyone will basically veiw you as a rapist...
as far as love: I do care about her but...will anyone believe that? Is SHE capable of love? Interested in a lasting relationship? Or just dating?
And what is autism-exactly defined? Social cues and norms are problems so...am I grossly misreading all her intentions? Maybe she's not coming on to me at all. And when she doesn't understand my subtle hints, there's the nagging fear that she DID understand and is ignoring my advances as HER subtle hint that she's not interested...when I need comfort, will she be able to sense that? Or be oblivious and appear uncaring as I feel
Worse that she doesn't notice...will she get mad at me for expecting her to notice? Will we talk about arguements? Or will she avoid that in favor of being alone because she is not good with people or conflict?
"Will she change her mind for no apparent reason because of autism? Is it worth investing in if I'm unsure?" Personally I decided that yes, it doesn't matter, she seems intelligent and rational
To me. idk wtf everyone else is talking about. A chance with her and the experience is totally worth it. Not everyone makes the decision that way. But my last nagging fear...if things don't work out, I don't know if I can accept that...wouldn't it be better to keep this amazing woman as my friend forever, than to have a blissful relationship for a couple weeks or months and then have them gone forever?
It's not always a luck thing...sometimes people just...are confused...although I just thought of a slightly more sinister one...maybe some think they CAN take advantage of you, then they are taken aback once they realize how intelligent you are, get freaked out as they think you can see right through them, and they run? Which is really a good thing. Eventually, someone comes along who decides almost none of that matters.
