I suppose you could tell him you wish he would initiate more contact, but he probably won't. Males are often not as communicative as females. Also, it may be true that he isn't as interested as you are, even if he genuinely like you. Males are often more practical than females, and honestly, long distance relationships are not such a great idea. Relationships normally require contact to thrive because people want to be connected, both physically and emotionally. (Out of sight, out of mind.) He may not be investing as much emotion into this as you are.

good luck...
