How to respond to an unresponsive texter?

Anonymous
I have been dating my boyfriend for two months, but we are going to be apart for a total of six weeks because I have an internship. It had been two weeks already and we have four more to go. Before I left he told me that he's not a big fan of texting because he doesn't like having to carry and look at his phone all day. He also doesn't check Facebook regularly. For the first week and a half that we were apart, we texted a few times through out the day at least four times a week. These were really casual conversations, mostly to check in and see how the other is doing. He wished me a Merry Christmas and I texted him that I miss him and he didn't respond. I then texted him the next day asking him how his holiday was and he didn't respond. It had been almost four days since his last response and I'm wondering if I should be worried. I've always heard that if a guy likes you he makes an effort to talk to you, and he was making an effort until recently. I don't really want to text him three times in a row without a response, but should I text him again? Was he just busy or is he losing interest? How long should I wait to text him or should I wait for him to text me?
