We had to move the date of our wedding from a Saturday to a Friday do to the number of guests. So it was a choice between sept 6 and October 25. We deceided to go with October figured it'd give us some more time to get things together. Our original date was sept 14. Anyways I'm having a problem because my sisters bday is October 23 n she says she goes away every yr during the wk of her bday n asked me to change the date to sept 6th. So right now we have both dates on hold the venue but need to let them know by Friday. My fianc doesn't want I change the date bc he feels we are caterering o my sister if we do so. So he pretty much gave me a choice of keeping the 25th or not getting married all. But if we have it the 25th my sister n the rest of the family I asked to be in the wedding won't b in it per my sister bc she'll choose to go away over postponing a couple of days to attend my wedding. What do I do???????? Help please
