My cousin is getting married the day after me. We aren't super close and when we do talk it's not wedding related. After I sent out STD's he texted me and told me. Anyways, yesterday I received the invite for the wedding but it was just addressed to me. His FW is the one who did the invites but they have my FH name from our STD. There was a cut out piece of paper in the invite with their registries listed so I'm wondering if maybe she just doesn't know the etiquette. I was planning on going to their wedding but would obviously want to bring my husband of one day. I don't want to ask and look rude but isn't it more rude not to have my fiance on the invite? On the STD I sent I had it addressed to cousin, cousins FW, and cousins FW's daughter. Should I just RSVP for both FH and I?
