It's my son's 7th birthday today. He has Aspergers and doesn't deal well with lots of people so we planned a small party with a few close friends (6 children of neighbours that he plays with a lot and his best friend from school who he has known since he was a baby). Nobody has shown up 
This isn't the first time this has happened, his 5th birthday we invited a few kids from school and he spent the entire afternoon sat at the window waiting for his friends to arrive
I feel awful for him, but he doesn't seem to mind, he is happily playing with dh and his new scalectric set.
All the people we invited rsvped that they would come, but none of them are home (I have been over to their houses and knocked and spoken to best friends mum who says he is too tired to come 
)
I know it's silly and he is happy but I feel like my boy deserves better and I'm sad for him that his birthday party has gone to pot AGAIN.
To top it off exh (my dcs dad) hasn't so much as texted to wish him a happy birthday. He is supposed to take him out for the day without his sisters tomorrow and hasn't made any arrangements for this. Ds hasn't noticed (probably because exh is a knob and never bothers to call on their birthdays) but it's still just shit isn't it?
Aibu? I know that he doesn't care, but I feel sad on his behalf
