I’ll try to summarise:
Every year we do secret Santa amongst each others siblings. So DH sisters & partner/husband is one secret Santa.
We are fairly close to DH family. See each other regularly.
We have 3 children.
DS’s (10) bday was in Sept. DH DS didn’t wish him happy bday or send a card / present. DH messaged her to ask if she had forgotten his bday. Her reply was in brief ‘I haven’t seen him that much, I don’t know what he likes, so I didn’t get him anything, lol’
They do know what he likes. Money is no problem for them.
They had, a few weeks before, bought her boyfriends nephew Who is the same age, a full bearded dragon set up.
I was pissed off. Simply a happy birthday would have been nice.
I got a message yesterday inviting me to the secret Santa between the siblings on my DH side. I don’t want to do it. I don’t want to spend my money on her when she can’t even be bothered to say happy birthday to my little boy. Quite tempted to say, I don’t know you well so I won’t bother.
AIBU and what can I say without causing a fall out?
