What is the etiquette regarding invitations when there is a family feud. Situation: My mother's sister (B) and her daughter (J) made some very hurtful and disgusting remarks towards my sister (maid-of-honor) via an online social forum. I have since cut all communication with my cousin (J). I plan on inviting my aunt despite her part in this feud out of respect for my mother, and my other cousin (H) who played no part in the feud. I do not feel that my cousin's (J) presence would be beneficial or add positive vibes to the day. My mother believes that I should invite my cousin (J) as well because, "she probably won't attend". What is the proper way to deal with this? Do I solely invite my aunt, and neither of her daughters? Invite my aunt and both my cousins? Invite my aunt and cousin (J) who was not involved? I'm trying to avoid WWIII. Thanks!
