My Sister Arrived at My Wedding With My Fiancé and a Shocking Announcement — But I Was Already Prepared

For years, I believed my fiancé Nick was the most dependable person in my life. He was charming, thoughtful, and easily won over my family when I first introduced him. My sister Lori especially seemed to adore him, even joking the first night we met that if I didn’t marry him, she would. At the time, we all laughed and treated it like harmless teasing. Two years later, Nick proposed during a walk in the same park where we had our first date, and I happily said yes before he even finished opening the ring box. Soon after, we began planning the wedding I had dreamed about since childhood. We agreed to split the costs and work together on organizing the big day. While I focused on decorations, flowers, and invitations, Nick offered to handle the contracts with vendors and venues. It felt like teamwork, the kind of partnership I believed would last a lifetime.
