DH has just been diagnosed with Asperger Syndrome. His mother was not keen on contributing to the assessment but eventually she did (made many excuses to delay it). She's made it really clear that he doesn't have autism and that she would know if he had that. I explained to her that there are different types of autism which manifest very differently, and Asperger is high functioning, therefore diagnosis is very difficult. It's been really tough for our marital relationship and life in general, and the last thing I or DH needs is someone close to him denying his diagnosed condition. She is one of those people who thinks she knows it all, dead stubborn and was even in denial when our DS had food allergies. I feel like having a harsh word with MiL because it's affecting DH badly and this is the last thing we need noe. Is she in the wrong or should I give her more time? She's known about him potentially having Aspergers for 3 months now, and I have been thinking about it to myself for about a year.
