My FI is very close to her parents and her brother - with many close friends as well. I, myself, am not. I lost my dad in 2008, the grandmother i was closest to in 2018, and my mother and I don't have the best relationship. While her and I get along and talk daily she is not completely onboard with a lesbian wedding. The rest of my family simply doesn't discuss it. I also recently moved across the country and don't have a ton of friends.
My FI had always dreamt of the standard wedding, while I have always imagined an intimate wedding/elopement with just my children. She is understanding about this since the idea of a traditional wedding without my dad devastates me. But she cannot imagine the wedding without her parents.... is it okay to invite her parents and brother, while on my side it would only be my children? or is asking one set of parents and not the other a breach of etiquette of some sort?
