DD (9yo) has been asked for the 3rd weekend in a row to a playdate she doesn't want to go on.
Backstory is this is a someone she's been friends with since reception but it's been a bit up & down over the years - short version is DD sometimes finds this friend suffocating (if DD wants to play with others there's tears/telling the dinnerlady/etc).
So now I think DD is at the point of trying to drift/cool the friendship.
1st request for playdate we were genuinely busy with a family birthday.
2nd request I made up an excuse
3rd time - what do I say?
I don't want to cause a big to do/fall out or make up excuses (probably shouldn't have done it last time) so any help composing a kind yet assertive message would be great.
I know I should be able to do this myself but I'm tired and just want to enjoy our chilled Sunday!
