Instead of randomly popping up to see this guy on the opposite side of the world, I think you should CALL HIM instead. It's cheaper, and you'll see if it's even worth seeing him face to face.
That's a lot of money. But would you rather have the hope that it could have been something or possibly find out it wasn't anything at all.
If they moved, did they really care about you that much? Contact them via the internet, safest way to do it.
If they say yes i've missed you, love you too then that's great go get your ticket and go get them!!
If they say yeah i've missed you but i don't love you, least you wont have spent money on a negative response.
find out how much the ticket costs and then spend that amount on yourself...you carnt go wrong
Id say do it!! what can you lose! because if you dont then there will be the "what if" question running wild in your mind like fire!
go for it sounds like a great challenge :)
Nah, just break out the ice cream like the rest of us do, it's far cheaper!
I would say screw it, or email her and tell her how you feel before going on such a huge trek.
