Some siblings invited to family wedding, some not- AIBU to not go?

[Waitaway1970]

Long story short, close family wedding- some siblings have been invited (including me) others not. When asked why some excluded, feeble reason given about one sibling and no reasons for others. Siblings feel we should stand together (and all not go). Not sure what to do as don’t want to rock the boat with siblings (already rocky relationships) and on the other side, snubbing wedding feels wrong too. To go or not go? Should add rocky relationships are just about healing so this is causing issues once more...

The people that aren't invited - are they your siblings or sibling to the B or G?

Could you expand and explain who the B&G are to you and your siblings?

Originally I though one sibling was getting married and some siblings had been invited, some excluded . This clearly isn't the case. I assume it is a cousins wedding ?

I depends on the relationship of the siblings and bride and groom. Who are the B&G to you? If it's your cousin's or other distant relation than I think YABU.

I really didn't want to invite one of my aunties to my wedding but her siblings (my dad and other auntie) made me feel like I had to. I didn't want to invite her because I'd not spoken to her for years and honestly invite her, her husband, and her kids took up more of my guest list than I wanted for someone who's made no effort with me at all.

So B&G would potentially invite everyone if it were their choice?

If that’s the case I would go. Why punish them because of their parents. But if they are of the same mind frame I wouldn’t, particularly if closer to my siblings who are affronted.
