My SIL is going out at the weekend for her birthday my DSis A has been invited and told me about it, and my other DSis B is going ( sis b and SIL are some what 'close') Dsis B won't go anywhere if me and my DM are going because she fell out with DM and then blocked my number (I still don't know why)
AIBU to think SIL could of at least told me about this and apologised for not being able to invite me as she wants Dsis B to be there, when she is the one that causes these problems in the first place?
It has honestly made me feel like shit as she usually invites everyone to events and who ever shows up, shows up! (Usually not Dsis B) and she normally 'slags of' Dsis B for how awkward and petty she is about it all...
would you say something or just get on with it?
