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...
