Am I Being Childish In My Relationship With My Fiance?

I have been with my fiance for nearly 3 years. He left for a funeral March 2009 and never returned. As strange as it sounds, we are still together. But we haven’t talked on the phone for a week now. We text each other back and forth. But is it wrong for me to be mad at him for not calling me to say I love you, I miss you, I love you, sweetheart but I’m busy at the moment, I’ll call you when I get a free moment.? Am I acting like a child? Or do I have every right to be pissed? I call his cell (which I pay every month) and all I get is his voice mail. I know he’s not cheating. I trust him that much. I am moving in the Spring (next month) to be with him, so there is a lot (A LOT) of planning to do..and I believe that he is avoiding the situation. Am I to blame? Or is he wrong?
