I think sending another text isn't good. For one thing it just increases the amount of static he's hearing from you. For another, it strikes me as controlling (like if you won't reply, I'll interpret your silence to mean things, that will teach you to treat me this way, if you don't like that grow up and respond or I'll find other ways to force you to). You can say I'm projecting your tone...don't you think he'll do the same?
Just get it done. He wants to be silent, let your actions speak instead of your words.
It's like the joke where the husband and wife weren't talking and neither wanted to be the first to apologize or talk to the other. Husband had a flight to catch at 7AM so he left a note for his wife by her glasses after she went to sleep saying "I have a flight at 7AM, please wake me up when you get up tomorrow". He woke up and it was light out, he was too well rested...sure enough, 8AM. He was furious and then saw a note from his wife saying "wake up!"
