Okay, you all know that tactic to not reply to a text immediately after a guy or a girl texts you but a man who is interested in you won’t play any mind games.
He will show you that he is available at any time and that he is glad you reached out. But if he ignores your texts for a day or more and you see him actively answering other people then he is just a loser who doesn’t deserve you.
Move on while it is not too late.
