My wedding is 3 weeks away and I was just informed by my nephew that he nor his sister are allowed to come to my wedding. My brother is non confrontational and doesn't want to upset the children so he chooses not to fight her on it (the kids are 16 and 21 by the way) It appears that the children are caught in the middle of their feuding.I do not have the best relationship with her but I almost feel like I should reach out to her in the hopes that she would reconsider her decision. Your thoughts?
