she also didn't act bratty on our first date. is that a bad sign?

wouldnt say shes ignoring. you didnt ask her a question, you just told her what days you're free. for a brat, you need to take much more initiative than that.

try uploading the screenshot into firetexts for exact suggestions, but in general, you have to be mindful of the fact that shes a brat. I have multiple vids on how to text brats on my YT channel
