AIO Friend Breakup?

AIO for kind of “ghosting” a girl that I’ve been friends with for many years now?

For a backstory, I met this girl when I was 17 or 18 and she was 18 or 19. She started dating a guy whose parents are best friends with my parents. I never really talked to the guy much, but really hit it off with his girlfriend when he started to bring her around a campground we go to. We bonded over so much & had such a blast together. Well, over the years I feel us drifting further apart. She’s gotten married, had 2 children, and has been fostering children in the foster care system. I have been in & out of relationships, dug my way out of an abusive relationship, found my current relationship, & had a baby with him. So, both of us have families. She’s a stay at home mom, I’m a working mom. No big deal. She is incredibly religious, I am not. No big deal. She doesn’t let her daughter listen to Taylor Swift because she’s feels her outfits are too revealing, I belt Taylor Swift in the car with my daughter because I think she’s such a positive role model. No big deal. She posts CONSTNATLY on Facebook about how hard parenthood is, that her kids are sick, and that she’s having difficulties with the current foster placement. She’s posts pictures of her foster kids with stupid hearts on their faces just so everyone can see the “good” she’s doing. Granted, I couldn’t ever be a foster parent, so kudos to anyone that does it, but why must it be plastered all over social media? That is someone else’s child that you are responsible for while they, and their parents hopefully heal.

Anyways, I feel we have drifted apart. The differences we had didn’t seem so significant, but they keep piling up the more we grow and age. She still sends me Facebook videos and TikToks, but I don’t look at them anymore. They are all videos related to being a mother. I love being a mom, but I’m so much more than that, and I’m sorry, but I don’t want my entire feed to be filled with parenting tips, mom-lore, or tips & tricks for potty-training. It’s her entire personality, and that’s ok, but I don’t look forward to seeing her anymore.

AIO for initiating a “formal break up” in the sense that I send her a message explaining all of this in a mature way? That I don’t agree with her views and that we just don’t vibe anymore? I’m getting married in October and having only 50 guests. I feel she expects to be there, but I haven’t broken the news. I feel horrible, but it’s just not a great friendship anymore.
