He Actively Makes Plans to See You…Again
Some men aren’t good at planning. You should learn this because they try, not because they haven’t. If you consistently need to ask him “so when are we hanging out again,” then he isn’t really interested. He may say yes every time you ask, but if he’s truly interested in you then he will take initiative. Please note: This doesn’t mean he needs to ask every time. It’s okay for you to suggest meeting up, but it shouldn’t be you asking four times for his every one.
Also, it isn’t a bad thing if he says he can’t meet up for a couple weeks because he’s busy. It’s much better for a man to make a commitment he can keep than to make a promise he will break.
