So, you got a flake to respond to a text in one second, and you didn't respond? Oh boy...
I mean, at this point it's over, but had you responded, even a couple hours later (doing her trick) she might've been in the right mood to hang out. You could've texted her back "Ok, what are you doing right now/tonight?" If she had "plans" (again) then proceed with moving on. The problem here is she's got so many other guys texting her that unfortunately losing you isn't going to mean a lot to her at this point, as you haven't banged her yet.
I do like your use of a polite "call out/goodbye" text though.
