I literally think people live in some weird world where they keep "secrets" from people that are blatant. There are pictures of her wedding in the family house - you think that should be taken down when i go home because "no contact".
Nobody has said wedding photos should be taken down.Nobody is keeping secrets.They've just respected your sister's decision and have chosen not to relay information to you.
She doesn't have to invite me to her wedding that's her choice. If people aren't going to tell me than that puts everyone in a difficult position so it's up to them to deal with it.
It doesn't put them in a difficult position.
Most adults would understand that someone's else's guestlist isn't theirs to share.
You can't expect a whole family to meet and it to never be spoken about in my presence.
Your family have chosen to respect your sister's boundaries.
It's not hard to appreciate why they have.
Who's the dock head now - my sister.
She isn't
No contact means you don't want to speak to that person, not that you make everyone's relationship difficult with that person after that.
Your sister isn't making everyone else's relationships different.
You are.
It's clear you feel entitled to demand your family keep you updated on your sister's life.
She doesn't want that.
Your family have CHOSEN to respect those boundaries.
You need to accept that your sister has chosen to go non contact and has her reasons, and your family have chosen to respect those boundaries whilst maintaining a relationship with you.
If you can't accept that I'm afraid it suggests clearly your sister probably has very good reasons.
