So.. the wedding is in 29 days, invites are out, whatever family drama happened is behind at least me and my FI. Long story short, because my biological mother said she's not coming because she won't be given 'red carpet treatment' (her words, not mine) despite having never been in my life until very recently (because just being invited wasn't enough), my sister, the only sibling raised by her, said that she wasn't coming either and did not want an invitation because if she comes, she won't be happy. So, I obliged and didn't send an invitation. (My mother, however, did say she wanted one to keep so I sent one to her and called it a day). (yes.... a lot of drama).
So my aunt, my mother's sister, yesterday (2 months after the fact) called about something else and then said, without stating names, that I need to send invites to everyone in the family and just know that when I look back 20 years from now all spats that I had with family were just minor.
I don't appreciate her being intrusive and a Johnny come lately (I hadn't spoken to her in years) but thought from an etiquette perspective, do I still need to send my sister an invite if I intended to have her there from the get-go?
