I think there basically three common scenarios in text game, for which I kind of thought out how to behave, and want to verify whether that behaviour makes me look confident and non-needyk:
1. First text you sent to her after you git her number and she is silent
Not too sound too needy I would wait out a day or two, and then proceed with something more funny/aggressive e.g. "looks like you have known me for a short while and I am already making you shy". Then after another no-reply I would (MAYBE) try last time after a couple of days and then I would delete the number
2. You exchange a couple of texts with a girl and then she stops replying
I would wait a bit and then send her something casual/interesting like "hey [nickname], looks like the town has been invaded by cyclists, almost got run over lol" or something funny. I would retry, if no further answer, with perhaps 2 or three more and then I would end with something more aggresive and then delete the number.
3. You exchange a couple of texts, you ask her, silence out OR she says OK to a date and then, when you reply with final dates she goes silent.
This is probably the most difficult as it is the most perplexing. I would probably wait a day or two and then retry, with a similar message to the first. If no reply, I would proceed as with number 2. from this stage, and retry if we rebuild regular convo.
What do you guys think?
