How petty would you be?

This is my second pregnancy and I’m all about protecting my own energy and boundaries. The timing of this pregnancy has essentially caused one of my oldest friends to fall out with me because it’s meant I can’t afford to attend her abroad wedding, plus baby would only be 2-3 months old and it’s a no kids wedding so it was out of the question.

The reason for our fall out is totally on her, I was super apologetic (even though you can’t help fertility, I had a mc before and it took us a year to conceive so I wasn’t about to pause for someone else’s wedding) I didn’t say any of that to her though, was just sorry. She made her feelings very clear, that I should’ve prioritised my money better so I could afford it (lol excuse me) and that she’s learned I’m one of those people who doesn’t prioritise their friends events, but that we have to move past it.

So because I hate confrontation, and we’ve been friends for years, I take her at her word and try move past it. Send her a good luck card and a text message on the morning of the first day at her new job, she didn’t acknowledge it. Checked in with her and how she was when I learned her dog was sick, she thanked me for checking in and gave me an update but didn’t ask how I was. Ignored my daughters birthday entirely (she always would send a card and gift, this year didn’t even message). Hasn’t checked in with me once throughout my entire pregnancy, despite knowing I was really anxious about it due to the previous mc. When we’re with our collective group of friends, she’s perfectly fine with me, but behind the scenes she’s totally cut me out I feel.

So herein lies my dilemma. We’re all in a whatsapp group chat, and had any of this not happened, I would’ve announced baby’s birth to them through that medium. However now I’m a bit like, why does she get to know? Why should she be one of the first people who finds out about my baby’s arrival when she’s demonstrated literally zero interest or care towards me/my family?

Would it be really petty of me to just tell my other friends who HAVE checked in regularly, haven’t left me on read multiple times, have actually responded and chatted with me like normal friends do? If I just message them individually with the news, but not her? On the one hand I feel like she doesn’t deserve to know, but then on the other hand I feel like I’m being just as petty as her if I do this.
