Ok, so my FSIL is adorable and creative and wanted to do something different than a traditional shower. She is throwing FI and I a wedding luau for his side of the family and some of his friends so they can be included in the party. It will be on a Saturday night.My question is, FI has a friend who is dating a girl ( for about 3 months) that has been less than nice towards me and who I don't care for in the least.....I gave FSIL a guest list with said friend on it. This friend has a +1 on his wedding invite, but the shower invite is only addressed to him, so would you think people would typically bring a guest to a shower? I do not want this girl there, but I'm thinking he will be bringing her anyhow....ugh.
