Should my daughter invite her half sister to her wedding? Her half sister had a complete melt down when it came time to take photos at her brothers wedding. Crying and hiding her face and walking away. Then yelling at her kids (flower girl and ring bearer) and leaves the wedding when the photographer would not stop the photos and just take photos that included the kids. Now accuses her brother of barely inviting her because she did not like her seating arrangement. Would like some outside opinions. Thank you
