My DD came back from school to say shes not been invited to a birthday party. Shes not too fussed as not keen on the birthday girl. BUT I think it stems from mum. Several months ago DD had a small party/sleepover with a few friends but not this child. Her mum sent me several aggressive texts saying her DD was crying, why was she excluded, what had she done to my DD etc etc. i explained it was a small party & I was sorry her DD was upset. She then says that my DD swore the invitees to secrecy about party. I questioned my DD and she had only told the non-invited one's BF not to mention it to avoid her being upset. Not a diplomatic course of action and i told her honesty is best policy in future etc etc.
Anyway, the mum started to blank my DD (DD told me about this even tho Id not told her about the texts) but was ok with me.
Now I feel she has done exactly what she accused me of by both excluding my DD AND swearing everyone to secrecy as some of the girls in the class asked if my DD had been invited and she dramatically said DONT TELL HER.
I am upset as this is exactly what I was accused of and it wasn't true! My DD only invited the girls she is close to and knew very well, this kid isn't one of them.
So, do i just leave it and act normally or do I use it as an opportunity to explain to DD just how you shouldn't act or do I confront the parent and advise her that she has just committed the crime she accused me of ?
