I had decided not to invite my dad's brothers kids (my cousins) to my wedding. There were a few that I wanted to invite but wasn't comfortable inviting all of them and I knew I would have to invite all or none. I'm also not that close with them. The few that I had wanted to invite made a big stink out of it and started posting negative comments on other family members pictures that they had posted on FB of my wedding day.
Now, one of them is getting married to which I RSVP'd yes to. She and her sister just recently had FB posts stating that "it's her wedding day, they're tired of hearing about who was or wasn't invited and to keep the drama to yourselves" in reference to not inviting some of their family.
This is so hypercritical, do I say something? Do I go to the wedding?
