I'm a little fuzzy on the details but this was a huge thing that happened a few months ago. The poster's FI was standing up in a wedding (I think) and the bride sent her a letter explaining that she wasn't invited because there was a chance poster and FI might break up (even though they'd been together longer than Bitch Bride and her FI) so they were only inviting married couples since those were the only relationships that were serious... or some other crazy reason for not inviting her. Poster's FI got upset (rightly so), told his friend what happened, friend had no idea his Bitch Bride did this. it turned into a whole Facebook thing with Bitch Bride's daddy coming onto FB to defend her shitty decision, she twisted FI's balls into a vise and he ended up defending her as well and telling OP's FI off and I think kicking him out of the wedding/un-inviting him. Knottie lurkers found her wedding page and went crazy on her, and OP eventually deleted everything because it just blew up the internets for a couple of days.
Sound familiar? I don't remember if it originated on Chit Chat or what. But we need an update!
