Don’t hang on the phone. If you were super busy with your interesting life you might not respond to a text for an hour or so because you’re busy. Do that.

Don’t ask him what’s going on - makes it sound like you’ve been anxiously waiting around to hear from him rather than YOU’VE been busy with your life!

Don’t initiate anything.You're conducting an experiment, to see if he’s genuine and if his actions can match his words. If you push for a meeting you’ll ruin the experiment because you’ll never know what he would have done on his own.

Again - read over my post about the kinds of guys who say that stuff.
