Ok I am going to tell you what a really good friend of mine told me about calling and texting them. Do not call or them because if they do not respond you will be hurt so in order to NOT set yourself up for pain, do not call nor text him. That way when he does call or text you YOU can decide what to do next.
I know with my H he just does not call or answer all the time. It has nothing to do with me. He does it to everyone. I dont know why, no one does. His brother got upset about it.
I just figure its a part of this weirdness. Let him surprise you. You can tell him you love him. Send it in a thought, not a call or text, as a thought you are sending to him.
