I have gotten so many numbers, online and IRL, that led nowhere, even if she does text back initially. Aside from recognizing when I have been too needy, perhaps betraying my desperate thirst for female companionship, I usually don't get into trying to understand why a given girl has ghosted out of my text inbox, just accept that girls are extremely flakey creatures, and soldier on. Like real life, Tinder is a numbers game. You have to cut your losses with a girl at the first sign of a rejection or red flag, and move on to the next one. Also, you must have multiple girls going at once, both as a hedge against this sort of flake, and so that she doesn't get the idea that you value her too highly.
She will definitely flake out on your date if she isn't answering texts.
