Even if the only reason you're texting him is because you're thinking about him, this kind of short and shy flirtexting typically leads nowhere. Giving a new guy your number and telling him to call can be iffy. Start with a text. Women tend to use this move as a way to make men jealous. But he'll see right through your needy outreach and move his texts on to the next. Anything beyond that reads "I'm just not that into you—or your texts." If you like him, gauge his interest by sending a light-date invite without hesitation. Try: "Don't know about you, but I predict I'll be parched after work Thursday. Drinks?" Any text sent while under the influence of alcohol, Ambien or a good Leo DiCaprio film is a bad idea! Conditions that lower our inhibitions make it more likely that we'll text things we otherwise wouldn't. If he only texts you past 10 P.M., he's just looking to hook up with you. The late-night flirtexter does not want to date you. Respond at your own risk. For instance, if he calls you and you like him, you absolutely must return the call. Texting back in response to his call reads uninterested. Things like "MTFBWU" (May the force be with you) and overzealous "LOL" usage should be reserved for texts with your tween cousin or BFF, not to a PBF (potential boyfriend). Doing this puts your secret fantasies at a high risk of being forwarded to all of his male coworkers. Throwing a "Buddy," "Pal," "Kiddo" or "Sport" somewhere in your texts usually accomplishes this. If he's smart, he'll take the hint. Girls interested in dating him don't typically call him "Kiddo." This is rule is especially important to remember when you're feeling lonely and vulnerable. Even if there were no sparks, it's just proper flirtext etiquette. But if you had the best date ever (we're talking full-on fireworks), call him the next day to say thanks. If he felt the same way, he will definitely appreciate the reassurance!
