My grandma is 90 and there will be a massive afternoon party for just two hours in a hotel paid for my mum, aunt and uncle.
All her descendants, their partners plus nieces and nephews without partners and one surviving sibling and two of her surviving cousins, one with husband. The surviving sibling and cousins will have one of their children with them given their advanced age.
Grandma does not want my cousin’s two stepchildren invited , they are teenagers who live almost exclusively with their mother.
Cousin has said her husband doesn’t want her to go with her elder child and their joint child.
Elder child’s dad has stepped in and insists that he will take child himself and sit in bar to wait for him.
My cousin, brother of this cousin is coming home from Japan for this.
My aunt has said she will make sure their joint child will be there as well.
What for you all think about this? Is cousins’ husband unreasonable.
