My sister ran away on Friday and got married, only their best friends and their children attended the wedding. I am happy for them as I know my new BIL wanted a small wedding.
They and all my and his family live 200 hundred miles away. They have chosen to get married 20 miles away from where I live and they have sent texts of where they will be visiting over the weekend.
AIBU's to be really pissed off that she has not even invited me and my family over to have a drink and celebrate their wedding. I am her only sibling.
