AITA for telling my fiancé's sister she can't be in our wedding until she pays me back??

okay so context, i plan weddings for a living 💍 and two years ago i did my fiancé's sister Rennie's (28F) ENTIRE wedding for basically free bc she was family, she just paid the vendors directly. except she never fully paid the florist, said she'd "handle it later," and i ended up covering the $800 gap myself so the flowers didn't get pulled morning-of bc i didn't want her day ruined 🥹 she knows this, we've talked about it, she keeps saying she'll venmo me and never does. fast forward to MY wedding planning now (me 29F, fiancé 31M) and she asked to be a bridesmaid!! i said sure but half joking added "once you pay me back lol" and she got SO defensive, said i'm "holding her wedding hostage" and bringing up old drama to be petty right when she's supposed to be celebrating me. now my fiancé is stuck in the middle bc his mom is saying i'm being cold over $800 when i make way more than that per wedding anyway. i said it's not about the money it's about her NEVER following through on anything. she's not responding in the family group chat and my fiancé's been weirdly quiet about it too 😬 AITA
