I (23F) just got engaged. My older half-sister (43F) has decided she and her children are invited. They aren't. How should I tell her?

Long story short, my half-sister is my father's oldest child and 20 years older than I am. I've never met her, she's never tried to have a relationship with me and has explained her reasoning as my mother never liking her. I've been completely content not having a relationship with her, we're Facebook "friends" but that's the extent of it. She's not close with my father either for what it's worth.

She lives in Florida, I live in Colorado and she's apparently decided she's invited and messaged me "you are inviting your older sister, correct? If it's not during the school year, we might actually be able to make it."

I'm wasn't planning on inviting her, and I'm especially not inviting her now that she sent that, but I'm not sure how to tell her I'm not inviting her or her children. I feel like I can't just say we're inviting close family and friends because she'll play the" but I'm your siiiiister" card.

It's really a space and budget issue, plus neither my fiance nor I want to meet my sister for the first time during my wedding.

I could just ignore her, but this is the woman who got upset that we weren't listed as sisters on Facebook. I'm worried that ignoring her could cause more problems down the road. The whole thing is just stressing me out, and I'm not sure what to do. Any advice?

TL;DR: Older half-sister I have no relationship with seems to believe she and her spawn are invited to my wedding. How do I tactfully tell her they're not?
