My brother and I are your average siblings. We get along, see each other a couple of times a year, chat about the important things, always celebrate birthdays with gifts to one another etc.
My brother is getting married and my SIL-to-be has no interest in involving my family in the wedding. Neither me nor my DC (primary aged children) have been asked to be part of the bridal party, which is a bit of a shame for my DC as they're little and would make cute flower girls / page boy etc, but it's not my wedding, so that's fair enough.
However I just found out that I haven't been invited to her hen party, which is at a spa. Now I personally think that as sister of the groom it is etiquette to invite me... I am a bit offended as I'd have hoped to have come along to her hen party to celebrate - she will be my SIL after all! If this is how their wedding is going I am starting to feel like she doesn't value me, nor care for my brother's family. My mum hasn't been invited either. AIBU? All the hen weekends I have EVER been on have always included the close family on both sides of the wedding party, not just the bride.
It bothers me as it makes me think she doesn't particularly care for me!
YANBU - it's a bit rude to not invite you
YABU - it's her hen do, let her do as she pleases
