Baby name

So a girl I know that I’m not SUPER close with, but still more than acquaintances, posted about the boy name they might choose for their baby... it just so happens that it’s what we’re naming ours and haven’t announced it yet. I’m due In 5 weeks, she’s only 5 weeks along. I texted her saying that was our baby’s name and she said “So?” like it didn’t make a difference... am I in the wrong for being kind of upset about it? I had her daughters name on my “girl list” before i even got pregnant or knew her but took it off because I see it as a respect thing. I don’t want to seem like a petty b-word but 😅😅😅
