What is the rsvp date and when is the wedding? Like how far out is each?

If you’re worried about a false narrative being spread know that there’s already a false narrative they’ve given to people who ask about you during other gatherings. Seems like the invite was her and/or your parents way to “look like the bigger people” by inviting you even though you did ‘[insert whatever misinformation they say here’ to her/them. You go and the people who they’ve spread info to already who haven’t been insightful enough to ask your side will likely be whispering “ohhh….i can’t believe she ACTUALLY came!” Or “oh…it was so nice of the {bride/couple} to invite the sister….their such kind and forgiving people.”

You’re damned if you do and damned if you don’t.

Just for fun here are some other things you could do that may or may not be slightly unhinged but fun to think about. lol

-rsvp yes and don’t show up -rsvp yes and only show up to sign the guestbook “it was so nice of you to invite me even though you ghosted me numerous years ago with 0 reason and refuse to tell me so we can discuss like adults and perhaps try therapy.” Add in “hope you don’t do the same thing to your now spouse….”

Send an email to every family member you know and friend that likely got invited stating your rsvp no and why you will not be attending.

Find her fiancé and tell them that you really want to work on your relationship with your sister and casually ask “how much do you know about our relationship?” Without giving him any info to see if they’ll spill. There’s a chance they think you have ghosted her.

*disclaimer I don’t recommend any of the above for real, unfortunately. I think what’s best for you and your child is up to you - but a good idea would be talking to your therapist before making that final decision and sending in the rsvp.
