Dear Prudence,
My fiancé and I are getting married in February on Valentine’s Day. The trouble is that my sister, “Sydney,” has lost her damn mind.
She is demanding that we change the date of our wedding because Valentine’s Day is the day her ex-husband ran off with her best friend. Five years ago. I told her this is insanity and that she needs to move on with her life. Now Sydney is furious with me and accusing me of having no regard for her feelings. I could not change the date of my wedding even if I wanted to. The invitations have been sent, the venue is booked, and everything has been ordered. She is now threatening to boycott the entire event. Should I try to talk some sense into her, or take this as a win?
