So, me and my Fi decided to just go through our preemptive guest list to get an idea of how many people we're looking at. About a third of the way through, we realized that his family is much smaller and closer than mine. His family side, cousins included, consists of twenty one people and they're all "must invites." Now, I know the rule "If you invite one cousin you have to invite them all," but does that mean both sides? If I invite my entire extended family I'll have over sixty people invited, not counting friends, and maybe ten would actually arrive and all from immediate family. I'm wondering if it's acceptable to just invite my immediate family if we invite his cousins. I'm not close to my extended family like he is, and I'm afraid the invites would seem gift grabby because I haven't talked to most of these people in years. I'm just unsure if this would be a slight etiquette wise. Any help would be much appreciated, thanks in advance!
