I Got Uninvited From My Friend’s Baby Shower. My Reaction Shocked Her

I’ve been close friends with April since college, helping plan her baby shower, suggesting names, and even making a Pinterest board for decorations. Then, the day before the shower, she texts me: “Trimming the guest list. Hope you understand ❤️.” Less than 24 hours before the event, I was suddenly uninvited.
Confused and hurt, I didn’t reply. The next day, I showed up anyway—quietly, with my gift in hand. People were happy to see me, but April looked tense, whispering, “You got my message, right?” I smiled, said it must’ve been a mistake, and helped with cupcakes.
Later, she texted, “You made it really uncomfortable. I wish you’d respected what I asked.” I haven’t responded. I’m still unsure how to handle it—whether to fix things or just accept that some friendships shift in ways we never expect.
