When a woman just sends a random text message and if it's cold, the guy who likes her will try to flirt with you so that you could just send a happy text. Being cold doesn't turn people off initially. Be cold in the beginning and then warm up.
There's nothing wrong with a "what's up" but if he said that he doesn't like it, then he doesn't like you. Just say a simple "hey" and if the person doesn't like it because it's not interesting, well we're not here to entertain. Absolutely not.
Also, there's nothing wrong with sending a text that you're having a bad day, it doesn't always have to be flirty. When you say you're having a bad day or when you feign weakness, it makes the other person cheer you up. By sounding sad or melancholy from time to time, it makes the guy step up and want to help you. By feigning weakness-- like you're acting like you're having a bad day and if the guy likes you, he's gonna make you feel better.
You can't sound happy all the time, you're not a Teletubby. You got to show a guy your dark side as well. Be normal and stop trying to always be happy. The best response is when you send a cold text message to a guy that likes you.
If you text a guy and he responds the next day, just send him a response of "I don't know about this". Another thing is to not respond fast or instantly, take a long time to text back--just like what I teach. Take a while to respond even if you're not doing something. If you're not busy, fake it til you make, find something to do. Be busy in your life but if you're not busy, play the game.
