I say the guy, if a girl texts first the guy could. a. Get annoyed or b. Txt back to not be rude. And if you do text him back you'll never know if he was into you. If he texts you first you know he liked it. And also.. If you don't text and wait for him he's gonna be wondering why you haven't texted and that'll drive him crazy and want to know about you asap ;) trust me it works.
