When text messaging keep in mind that, just like in face to face encounters with a woman, there are rules to know and follow.
Rule 1: Never text to dodge a real conversation
A lot of men figure that a text message is much more safe than a phone call. True, but it will not consistently lead you to your goal. And that goal is to set up a date. The chances of seeing her again raises drastically when you get her on the phone and make plans as it builds comfort and familiarity.
Also, if you're texting because of your fear of interacting with this woman, then how will you ever hope to interact with her comfortably face to face?
Rule 2: Do not seek responses for validation.
Remove value seeking texts like, "What up?" or "What are your plans this afternoon?" Texts like this scream neediness, make you less attractive to women, and do not help spotlight your fun characteristics.
Take a look at some sample texts that are have been repetitively tested and proven effective...
"Your twin just walked past me wearing a purple sparkle fanny pack"
"Hi nerd! I'm sure you're operating at a level of 100% nerdiness today :) "
Rule 3: Abstain from over texting
She may be the only thing on your mind, but don't let her know that. Don't scare the bunny away! Text once, and if she replies, you may do so. But if she hasn't, then wait until the next day before trying again.
Try to place some space between text responses. Keep in mind, non-neediness means sexy because she will see you are in demand and have other romantic options.
When in doubt, pace her. If she texts you back right away, you can text her back right away, but if she takes 10 minutes, then so should you.
Bonus Texting Tip: Use texts to invoke the law of familiarity.
Once you have her number, text her as soon as you can especially if she is standing beside you. The situation is hilarious in itself plus give yourself triple points if it's an inside joke or funny text. Here are some...
"You have my number but please limit yourself to one per day ;)"
"Who is that sexy man you just gave your number to?"
Once she saves your number, you can be confident she is interested. But even more important, when you call later, she will have your number and caller id appear. There is even more chance for her to pick up the phone to a recognized number.
