I had a girlfriend who urged me to "not think about it" like I would have cancer or something similar. This made me extremely angry since I've worked on not letting it control my life my whole life and I told her it doesn't work that way. She then stated that she doesn't want me to be me due to my difference, and I had to lightly explain that I am me thanks to my difference.
She didn't understand that if I hide or suppress my AS then i wouldn't be the one I am and in the ways that I act and utter myself.
She was really bent on changing my course of thought and the view on the things I did together with her. (she was NT, go figure...)
And just to add, I did a large amount of things with her that would put me miles outside my comfort zone, I both did it for myself and for her but she would never understand that I needed to recharge my energy and then threw a emotional fit and claimed that I wasn't willing to do things with her. This broke my heart since I had done a lot and often, but I guess my speed in social interaction and general activity wasn't matching hers.
Shame really.
