dude just be unpredictable about it don't think too much about just go on doing what you are doing on text when you are done, don't stop what you are already doin tho answer the text this way its more natural and not planned because even if you do that wait longer than her or next day rule its gonna be on your mind and its like a burden so just go on living your life and when you are done text her it works better this way, but if she gives short answers try to do the same or else it'll feel like you are really trying to grab her attention. Last thing is be goofy, a little nerdy in texting using emoticons to brighten up your messages a basic rule is try to make her smile with your every text.
