I seriously doubt this is going to turn out well for you if you need a 13 page topic full of advice on how to send a girl text messages lol
Truthfully speaking I don't think anyone here is qualified to give you advice on how to interact with a girl. They're all very different but all very much the same at the same time. Some will respond to you better than others, some are more complicated than others. It's basically up to you to figure her out by yourself. Confidence is key, as it is usually the difference between persistence and desperation, and girls can read that stuff like a book. If you're shaking and sweating and losing your mind because you can't figure out how to respond to a message, then you're doing it wrong. The worst thing you can do is preemptively put the pusillanimous individual on a pedestal.
