My experience was really bad.
Since I do very little talking - she would frequently take offence and accuse me of trying to make her angry, of being silent just to start arguments, etc. Whenever I did say something, she would throw it back in my face and treat me as though my words were idiotic and meaningless. Which of course led to me becoming even more non-verbal ...
She would openly ridicule me in front of her family and friends.
I spent a lot of my energy trying to help and comfort her, since she would meltdown whenever things weren't going her way. She took out a lot of her anger against me. I honestly thought it was a good idea to let her do that, for me to be a (metaphorical) punching bag. I just wanted her to feel better about whatever was bothering her.
The problem, however, was that my kindness was not returned. Basically, she had no concern for my feelings. I was going through a really rough time and, well, her response was hostile and uncaring.
I've been through a lot of bad things in my life. But that experience left me feeling more dehumanised than anything else - to the point that for years after I could not talk to other people.
I do not want anyone to think that all ASD relationships will end up like mine, or that all ASD people, male or female, will behave in this manner. But I am unconvinced that ASD-ASD will work better than ASD-NT simply because they have the same condition. ASD people are supposed to be less judgemental and more understanding? - my experience seems to disprove that idea.
