Is it okay to tell my LDR boyfriend that we've been communicating less and less, day by day?

I'm 27, f. The last time my ldr boyfriend called me was 8 days ago when I was travelling. Even the messages have been declining to 3-4 messages a day. Everytime I tell him this, he tells me he'll communicate with me more, but he doesn't. He doesn't even say that he loves me.
