My husband and I are currently expecting our first child. We are having our gender reveal on Saturday which both of our families have known about since September. Today, my mother-in-law called asking if her best friend could attend because her plans have changed and she is no longer staying overnight and she doesn't want to travel on her own (my parents live about 2.5 hours from where she lives). My husband's mom is the only one from his family able to attend. His dad and step-mom don't really like parties and don't agree with us finding out gender, his sister has a newborn so with Covid she isn't comfortable attending, and his two brothers live 8+ hours away. My husband is feels I'm being selfish because I don't really want his mom's best friend (who I've only met a handful of times) at our gender reveal while my parents, siblings & their spouses, and my grandmother and grandfather (who are like second parents to me since my mom had me very young) will be in attendance. I just waited it to be close family which my mother-in-law's best friend is not, but I also don't like fighting with my husband over this. So do you guys agree that I'm being selfish for not wanting the best friend at our gender reveal?
