So, our STD's went out about four months ago and we sent one to each of my FMIL's sisters (she had three). Since that time, one of her sisters has passed away and it has caused a riff between her and the other two sisters. My FI doesn't speak to either of his aunts and we only sent the STD's to them at FMIL's request. This weekend, she asked me NOT to send them invitations, because she "would have a better time if they were not there" and "does not want them to be present". I don't know what to do! I know etiquette says that anyone who got a STD gets an invite, and that's my instinct, but I also don't want to cause a rift between me and FMIL. FI doesn't talk to either of these aunts, and the first time he had seen them in years was at his aunt's funeral . . . any advice, ladies? Please help! I feel stuck between an etiquette rock and a FMIL hard place.
