Is AUTHOR wrong in the post ? POST : My Cousin, who I'm very close with, is having a wedding this year. My fiancee's birthday coincidentally falls on that same day, and she's upset that I would want to go to this wedding instead of celebrate her birthday with her. Am I being an asshole for wanting to attend my cousin's wedding over my future wife's birthday? We haven't quite come to a conclusion yet, and she's been moody for 2 days ever since I brought it up.

For clarification, we are in our mid-late 20's. She has always taken her birthday, and other people's birthdays, very seriously. Even asking if she can celebrate her birthday on a different day has been a no-go. Am I in the wrong here?
