First of all, it is sad that anyone only wants to talk to you through text messages, email or phone. If someone loves you or likes you, they would "want" to be with you "in-person", "in-real-life" and wouldn't need to rely on text messages, emails or just occasional phone calls.
As far as signs go? You would rarely receive any messages from him.
I suggest you "move-onto" someone BETTER than him. Or, just stay by yourself without him, and live your life doing what you love doing and feel happy about it.
