When you like a girl and there's some sort of playful interaction but you start texting and you don't get the same feedback:

- she never texts first

- she answers questions, laughs but she doesn't contribute a lot to the convo, which drops at some point every time.

Do you take that as a a sign of no interest and drop it or you ask her out anyway? Do you text a lot before asking her out, looking for signals, or do it rather soon?
