I hope i'm not speaking out of turn, but hopefully this is useful to someone.
My mum has aspergers (undiagnosed but I am pretty sure. Her brother definitely has it and it just fits).
We clashed terribly when I was a pre-teen and teenager, we just did not understand each other. I thought she did not love me. From my point of view, she gave no obvious indication she loved me - she never said it, she was critical of me and seemed to me wholly uninterested in my life or my friends, outside of being interested in my academic life. I craved her love and attention and a lot of our arguments were - I now believe - due to me preferring to be arguing than ignored.
What seemed irrelevant to her - small talk for example - was important to me.
It was a difficult time for all the family.
As I got older, our relationship improved but it wasn't until I was in my mid 20s that I understood that she does in fact love me.
And it wasn't until I was in my mid-30s that I understood that she has Aspergers. Once I understood that, it made a big difference to me to understand that she is the way she is because of ASD not because she doesn't like me. Our relationship has improved massively now I understand her better and know that her behaviours that made me feel so rejected are not from a bad place, she's not actually even rejecting me after all.
The closest we have ever got to discussing it us my mum closing a conversation down about whether DS might be on the spectrum by saying "I don't think it's useful to be given such labels".
I can see how she would think that. She's a high achiever and has been hugely sucessful. However it has benefitted me enormously to understand why she is how she is to me, I feel much more accepting and protective of her even.
I also appreciate her fantastic qualities now too, I took them for granted when I was younger (perhaps that is just youth? !) She had instilled her thirst for knowledge and sense of fairness and justice in me for example and I will be forever grateful for that.
She suggested once when I was a teen that we went for family counselling I wish we had, I think it could have helped in trying to understand each other.
I wish she had been diagnosed and had shared that information with me. It would have helped enormously if I could have understood earlier. Also maybe she could have got relevant help and advice with managing our relationship.
I hope this post is helpful, if it helps anybody avoid the rows we had that would be amazing.
