You guys sound like a bunch of school jocks who try to act way too try hard lol
Theres nothing wrong with keeping contact with a girl, I know guys who blow girls phones up constantly and send the good morning messages all the time and they do fine so relax, if she into you then it doesnt matter what you do, obviously don't overdue it but you get the point.
You guys need to stop acting like if you do this or do that then you wont get the girl lol if you dont get her it has nothing to do with something as small as "texting" between dates, its because shes just not into you.
When I was younger I've had women who I called and texted lots and they fvcked me, sucked me, bought me things, let me drive there car around ect. The way you carry yourself is waay more important
