He gives you excuses why he didn’t call you. He’s busy, he’s stressed at work, he has a million things going on. If he’s into you, it doesn’t matter how busy he is, he’ll take EVERY second in a day to reach out to you, even if it’s just to send a quick text. If a guy says he’ll call you tomorrow and then doesn’t call until two or three days later, it means you’re just not a priority to him and he’s neither here nor there. If a guy is into you, he’ll call when he says he will.
