No, just because he is not texting you first doesn't mean he doesn't like you. However yes it's a little strange though. It's possible he is shy, it's also possible he is not very good at texting, doesn't know how to start conversations.

If he never Initiated contact then I'd assume I was never on his mind, and he was only responding out of politeness. It's a sign of indifference
If I text or call most of the time then I'd refrain from calling and texting as much. I'd need to know if he was as eager to chat as much as me. I'd only know that if I stopped texting/ calling as much.
