I'm just a little curious as to where he is exactly. It sounds like he isn't in a high tech world right now, which could easily explain the lack of communication. If he is in a more westernized area with internet cafes, libraries, etc, then I also am having trouble with the lack of communication... Also, when did he get to where he is?

I have been in a long distance relationship myself, so I completely understand the sudden fears that seem to creep into your head when you're far away and communication is slim. Granted, I never went a week without hearing from him (he was in Germany for a few months, but usually just in another part of the US, so plenty of access to internet).

Maybe he is simply not one who uses computers a lot. Maybe that explains his lack of communication, leaving his dating profile up, and not friending you on facebook -- he simply never goes on the computer for personal reasons.

It sounds like you are happy with him, so I would try not to go looking for trouble. Go with your gut, and if something feels REALLY off, then perhaps re-evaluate things. But don't go looking for trouble if you are generally happy. Try to be patient while he gets settled and see if this whole communication issue clears up.

Good luck!
