Background:
This girl and I used to be great friends when we lived in the same city. She moved away for a bit and then moved back and during that time I let her stay with me without charging her for anything. She was also in the middle of buying a car and asked her other friends if she could burrow their car for a few errands, everyone said no because of insurance liability, I on the other hand let her burrow my brand new Porsche for a whole week, no questions asked. I bring this up only to show how close we were. While we both lived in the same city everything was great and we never had any issues, at least that I was aware of.
Now:
I moved to a new city a year ago and got engaged to my long time boyfriend. The minute we got engaged I started planning the wedding and bachelorette party. I sent bachelorette invites and all my bridesmaids and friends agreed to the set price and RSVP 'yes'. She ended up backing out last minute saying she couldn't afford it anymore because she wasn't drinking and wanted to start IVF treatment ASAP. I was upset because she knew of the party months ahead and we even did it in her home state so she wouldn't fly, which means it was a destination bachelorette for everyone else because she was the only out of the group that had a lower budget. I ended up eating up the cost of her not coming instead of making my other friends pay more to make up the difference. Either way, i didn't say anything to her so she didn't know I was a little upset. I recently found out she came out to the same city I'm at for a concert and to hangout with other people, but did't tell me she was here. I messaged her and said "oh you were in X, would have loved to see you" she responded it was a short trip, which it may have been, but as close as I thought we were, I would have at least texted saying "in your city, would have loved to hang, but its a short one". The last nail on the coffin for me was when I saw she flew to a different city from hers to attend her other friend's bachelorette party who JUST got engaged and planned her bachelorette last minute. She was also drinking and partying with them so I feel she just lied to me about the entire thing. This is also a girl that told her "you can't burrow my honda because I don't want to be responsible if you crash" meanwhile I let her burrow my brand new 80K car for a whole week. I just feel like she only used me for what I could provide for her while we were both in the same city and now that there's no use for me she has just distanced herself.
My fiance thinks I'm being petty for uninviting her and I should let it go, but I'm just tired of unreciprocated friendships and I feel like she's one of those. What is the etiquette on uninviting someone to the wedding? should I text her or just remove her name so she can't RSVP?
