My mum and her partner of 20+ yrs (lets call him X) are probably going to split up over the fact that X refuses to believe that my 6 yr old is Autistic (thinks he is just naughty / me and DH are too permissive etc etc).
X has banned my 6 yr old from their house (actually his house that my mum lives in) when his grandchildren are there - my DS is a danger to his grandkids, apparently
.
My mum has had dozens of heart to hearts, discussions, arguments, tears with X over the months which have amounted to nothing. He will not be moved on it and, sadly, his family (who had become my family, too, over the years) are siding with him (unbelievable).
I am devastated, to be honest. It has now come to a head over Christmas arrangements and my mum is in absolute bits about it all and I think she is going to leave him.
This may sound garbled and is only a tiny bit of a long and sad story.
Just feel gutted for my mum, my DS, our lives. 
How can a grown man show so little compassion ad understanding for a child? And so little care for my lovely mum, who is heartbroken and has been put in an awful position.
