For background: I have 3 children, 2 of which are my partners biological children whereas my eldest is not. Me and my partner have been together for 7 years and 3very single year without fail, his gran will send his biological kids a birthday card and money but never my eldest. This hurts, my partner has taken on my eldest like his own, he's been around since she was 2 years old. Everyone in his family accepts that she is part of the family but not his gran.
She's been told before how upsetting this is and always makes an excuse. Last year she was told by both my partner and his dad about how much this upsets us but once again, she's done it.
Am I within my right to send back the card and explain that I would rather nothing at all from her unless she accepts that my 9 year old is part of the family.
Ive never done anything to upset her, I've always been kind and fair but for some reason, she really doesn't like me or my daughter.
