No offense...but you guys give some horrendous text advice. "Hey...whats up?" Will probably get you no where. You are better off going with DJ Damage's approach than that.
But I agree with neither anyways. Girl's rarely pursue guys - because it's not their job - and if they're of any quality at all - they have plenty of options. Women like to be pursued...if done the right way it turns them on. DJ Damage's approach is good if you don't want to hurt yourself (but it's not a good strategy for looking for high success rates with women). You're virtually eliminating yourself from most relationships because you don't want your ego to get hurt.
When it boils down to it there is ONE reason why you are running phone game on a girl -- to meet up with her at some future point in time. Text game - specifically - is only ran effectively with the use of banter...you don't use comfort nor do you use boring things (i.e. Hey whats up?). Besides I'd rather have fun by saying something stupid back to her...something unpredictable. She says "Hey" I say something like "Hey ho baby toe...have you ever thought about drawing me an awesome picture...I like dinosaurs
". That says 1) You're not making the thing she didn't agree about a big issue and 2) You're fun to talk to over text.
Here's the main thing to remember with women - you do best when she feels like you're not trying but you're pursuing.
