AITAH for not inviting my cousin to my wedding?
I (25 F) am getting married this November to my partner (26 M). I have sent out my invitations to everyone except to a cousin of mine. She has a son (11) with autism and I love him very much however last year when my brother got married she brought him along and kept interrupting the ceremony by screaming, crying and running. I understand that he can’t control however she has claimed that she can’t find a babysitter or leave him with her in-laws (who are not invited to my wedding). I considered making it a child free wedding however my partner’s niece (8) will be my flower girl. I told her the reason why as to why she wasn’t invited and although she said she understood, she told her family who then started calling and texting me calling a horrible cousin and aunt. I brought this situation up to my cousin and she said that I am wrong, that I still should’ve sent her an invitation and she would’ve decided if she will be coming with her family or not. Do I invite my cousin and her family and potentially ruin the peace a wedding ceremony should have or just let it be and deal with it later?
