I'm getting ready to send out my invitations and am not planning to invite some of the cousins I'm not close with (as in haven't seen them in 20 years because they live across the country). Here's my problem. One of the cousins I am close to was invited to the bridal shower next week and, mistakenly assuming everyone else was invited, asked another cousin to go in with her on a gift, and she agreed. Am I now obligated to invite the other cousin to the wedding, or can I just send her a nice thank you note for the gift?
I don't know that my cousin would come to the wedding even if invited since she would have to travel and is broke, but it wouldn't surprise me if she found a way to come—and she would cause a huge disturbance and drive me crazy if she was there.
