The past few years my parents have hosted big family celebrations for all of my siblings’ (and their spouse’s) birthdays (to which I’m expected to attend and contribute) except for me / DH. There’s always an excuse - they booked holiday, or there’s another event, or my siblings can’t make it and there’s never any effort to organise it another day. Something that never happens for the others - their birthdays are ALWAYS celebrated even if 2-3 weeks out.
This year there isn’t even an excuse - they just can’t be bothered. DH said he’ll organise something then ask them to attend but even he’s getting fed up because he knows they’ll just come up with another excuse. I never get a card or a gift - just a text if they remember.
I am the Scapegoat so I should be used to this by now. But it still hurts.
