1. Nothing

Absolutely nothing. You're better than that. Although you're somewhat panicking and it sucks because it feels like it's the end of the world, the best thing to truly do is nothing. Don't text again, don't rant about it to anyone else (word of mouth can spread fast sometimes) and don't sweat over some guy who can't respond. If he wants your time, he can work for it.

Make sure to remember who you are and what your value is. I understand talking about this seems dramatic and unnecessary, but sometimes it really does take a toll on peoples attitudes and mental health, especially when you think this guy may have really liked you back and doesn't respond out of anywhere.

Make sure to think about the possibilities as well. He's probably doing homework or hanging out with his friends and will respond after. Back when my boyfriend and I were a "thing," we mainly just Snapchatted. And sometimes he wouldn't respond to me and yeah, it sucked, but I kept my cool. And a quick tip, if he wouldn't respond for a couple of hours, then I'd make him wait for a couple of hours for my response to show him I have better things to do as well, and that lured him in some more. Now look at us, we've been official for a year and a half.

But seriously, you may feel like you have to do it, but do not double text (or snap in this case). There's no better way to destroy a possible future relationship than for a guy to look at his phone and see unwanted needy messages when he was most likely busy with something. If it's meant to be, it's meant to be.
