DC is marrying someone from another European country and they plan to get married there. They have chosen their wedding date for the summer without a courtesy check with myself and DH. DH is a teacher and they have chosen a school day, which is pretty tricky for him. Because the wedding is in another country, travelling there and back will add further days to the wedding. They are refusing to consider other dates and say they have made their mind up with no explanation to us about why this date is essential. DH and I feel pretty gutted that a) everything has been arranged without telling us. b) they knowingly chose a date they knew DH will be teaching. AIBU?
