So I sent my save the dates out early because my wedding is on a holiday weekend of this year. Since I have, there have been some acquaintances that haven't really kept in contact (me or them) or there are people that I have realized aren't as good of friends as I originally thought when sending out the STD. What is the etiquette in not sending these people wedding invites after already having sent them STD?? I feel like I wouldn't really be sad if the friendship was severed from them not getting an invite, but I definitely don't want to be rude. Help please!
