I am also wondering if it could truely been time restraints. It is easier to call Mom or sis just to say I am coming home tomorrow, gotta go (and cut them off), than it is a girl friend whom you haven't seen for two weeks. Rather than get into a rushed conversation and perhaps hurting your feelings by cutting you off quickly, he sent you word that all was well, and he will have a long and meaningful conversation with you when he gets home.
