My mother has ASD as does my son. My mother and I clashed terribly when I was in my teens and early 20s and a large part of this was that I wanted an emotional connection from her that she was unable to give or recognise my need for. I genuinely thought she didn't love me and wasn't interested in me until I was about 23.
Working out she's on the spectrum has helped our relationship loads as I now understand that the way she acts towards me isn't a lack of love - not at all.
It's not ablelist or unkind to recognise that the way my mum related to me was really tough for me as young person. I had a deep need for an emotional connection with her, and for her to at least appear interested in men and the things that mattered to me - and it hurt that it wasn't there. The flip side of that was that she found me really hard to cope with too.
I hope this doesn't offend you! But this was my experience. Understanding more about neurodivergence has helped me see it wasn't personal, she doesn't choose to not be emotionally available to me, it's just the way things are.
I wish we'd both known that she was on the spectrum when I was a teen and had some insight into what that meant for our relationship as it might have made my teenage years more bearable for all concerned!
She doesn't understand the effect she's had on me, and tbh I'm not inclined to explain it as I now understand she can't change it, and I wouldn't want her to feel guilty about it.
On another tack entirely, my mum is a great role model for my son, who has ASD. She's a super-smart high achiever and has a nice life and he looks up to her (as do I!)
I certainly don't think my mum is sub human, she's my shero! I love her and think she's incredible in loads of ways.
FWIW I have ADHD and I know that impacts on my family in different ways. (I think I'm aware of how, but you'd have to ask them to be sure).
