I've seen so many shitty posts on text game, I decided I would lay to rest all the misconceptions and poor advice by giving some actual USEFUL advice.
So many other posts I've flipped through summarize texting as unimportant, or merely a tool to schedule and confirm a date. This is completely the opposite of the truth. The vast majority of girls LOVE texting FREQUENTLY. They do it all day long with their friends. If they're in a relationship, usually they do it all day long with their boyfriends. There's no reason why you shouldn't be texting back and forth the same way. Of course there are exceptions, some girls are busy and don't have time to exchange 100 texts a day. But still, if they're interested they will make the attempt when they have time and will appreciate the thought.
Let's say you meet a girl on a Thursday night at a bar and schedule a date for Sunday. That's all day Friday and Saturday that she won't be seeing you or talking to you. By the time Sunday rolls around, do you really think she's looking forward to seeing a guy she just met at the bar three days ago when she was drunk? NOPE. Chances are good she will flake by the time Sunday rolls around if you haven't stoked the flame somehow either via text or actual phone coversation. Or she'll go on the date and be generally apathetic about it.
Texting is momentum. If you have no momentum, your date will start off slow and awkward, because lets face it: you're basically complete strangers. If you DO have momentum, you'll both be walking into the date "in state" because you're looking forward to the date and you've become acquainted and even more attracted to the other person through text messages.
What the fuck should I text her?
Text her e-card memes. Ask her what she's doing right now. Ask her what she's wearing right now, followed by telling her you're wearing a revealing sexual outfit (silly but setting the sexual groundwork). BE AMBIGUOUS. Make her wonder whether you were being sexual or not. Give her soft-tosses for sexual convo. If she asks what you're doing right now, "I'm about to get nekkid and hop into the shower."
If she reciprocates in kind, she's interested. If she reciprocates and even initiates texting on her own, she's seriously interested. If she gives one-line response or responds infrequently, just ask her straight-up: "I'm not feelin' the love here, I'm throwing in the towel unless you give me a good reason why an awesome guy like me should stick around (add winky face or some emoticon bullshit)." Remember, YOU'RE the one who needs to be convinced that SHE is awesome. You already know you're awesome, right? If she's interested, she will apologize profusely and change behavior, if not, move on.
There's plenty more to be said, but that's a start at least and a huge improvement over the other dumb shit I've seen on this website
