My fiancé and I are planning a semi-formal relatively small wedding.
Do I need to invite all of my first cousins if I invite one? On my mother's side I have two uncles and a total of five adult/almost adult children. I'm not close with any of them really. I was invited to cousin C's wedding and I've always been fond of my baby cousin S, I've also spent more time with her family than my other uncle's, so I am considering inviting those two.
Another factor is that seven years ago my mom found her birth family and she has gotten close with them. She has asked to me invite her two sisters, who are very sweet, and her brother, who I have never met. My mom never asks for anything so I have agreed to invite the three of them and their SOs.
As I mentioned we're hoping for a fairly small gather, although with my fiancé's big family we are rapidly approaching 100 people, which is a lot of pressure for me socially (introvert) and adds up quickly financially.
I don't want to be rude or upset anyone. Any advice is greatly appreciated.
