This was my thread from last year. Essentially SiL only invited my younger child to the pantomime. My younger child is her niece. My elder child from a previous marriage was not invited.
This year younger one will go but elder will have an alternative outing. I am not happy but DH insisted.
Every year we go to a laser/light show at a cricket ground . We go with a family we met when my eldest started primary school but they have now moved.
I asked my sister-in-law to go instead Stupidly I did this as I wanted her to see my elder child as part of the family and see her interacting with her sister but now younger one has been invited to a party and is desperate to go,
Sister-in-Law has now said that her kids now don’t want to go although her elder one will be there helping on a stall with his scout group, as they were only going to see the younger one even though elder is nearer their age. Fucking blatant.
DH doesn’t know what to say, he feels if he speaks to his sister and they start to include elder it will be false setup on insecure foundations.
I think because he has agreed to pantomime they are now given carte blanche to not consider elder one.
There are two new grandchildren coming this year and I think elder child will be completely disregarded.
In our house we are happy together but I am so miserable when things like this happen.
