Personally, 2 weeks is a bit long for him not to contact you even if his pc is not working......
he could atleast text you or call you..........
And also, do not bombard him with emails and text messages....you don't want to come accross as a bit desperate...
There's always a way he can contact you if he really wants to....
Besides, it will be hard finding a person who doesn't want to be found....
it's just like waking a person up who is not really asleep but only pretending to be asleep....
I suggest you let him be and do not obsess about it and do not wallow in misery about this guy.....
just live your life and have fun with what you have now and keep your self busy......
bond with your family and your friends, focus on your job and keep your mind occupied....
If one day he suddenly re-appeared, listen to what he has to say and his reasons for being gone without keeping in touch.....
Then that's when you decide if his reasons are valid or not....
