So FI and I are trying to get our STDs out this weekend and there's a few people who are in relationships (obviously will be inviting them), but because we don't know how serious some of them are right now/where they'll be in 6 months...do we include their name on the STD? For instance, FI's cousin lives out of state and he has a GF. They don't live together and we aren't exactly sure how serious it is because FI doesn't see or talk to him that often. I don't want to put her name on the STD and then have them break up and either she thinks she's still invited, or say he breaks up and gets a new GF and then he thinks his new GF isn't invited....so I'm not sure what to do there. What say you???
