My fiance and I have been planning our wedding for a couple months, though I only got officially engaged a few weeks ago. He goes to a military academy is not allowed to marry before graduation, but we will only have 30 days after he graduates to get married and get moved across the country to wherever the Army sends us. I announced my wedding date a few weeks ago to my sorority, and one of my sorority sisters announced tonight that she is getting married on the same day I am. The chapel and minister have already been booked with substantial, non-refundable fees and our date just isn't flexible at all. I'm not sure what to do because she doesn't seem to be respectful at all of my wedding! It will be the last time I will EVER see my sisters and I feel like it is just going to make my wedding day stressful.
My question is, is it rude to ask her to move her date? She wants to get married in a city an hour away from my wedding location and my sisters wont be able to come to both unless she gets married in the morning.
