Presumably you've talked to your wife about your feelings on the move right? I mean really getting things off your chest.
This might sound silly and obvious, but from personal experience and from seeing a lot of marriages, relationships get in to trouble because of such a move to Hong Kong, I would recommend that you do it, if you haven't already.
Sometimes, a spouse/partners don'sen't fully realise the impact such a move is having the other who may for instance be just going along with it not to rock the boat. Not saying that this is happening in your case, but its something to bear in mind. Also, its true that the first few months can be challenging and this can compound any uneasy feelings you are having now, and later get vented against your family members an cause friction.
Loz_2: Thanks for you concerns. Like most couples we're talking things out about many aspects of life. It's always the goal that matters most. Having that in mind should help with everything else.
We've been in HK for two weeks and still haven't found a place to rent. Been nutty trying to figure it out. Balancing out the facilities and pre-school for the kids (2 and 3 YO), wife's job in Tuen Mun and where I'll probably find employment for a writer/ESL Teacher, HK Island (?).
The heat's is doing a number on me. Fall without cool breezes...weird.
As a recent arrival I cant add much to what people have already said-just give it a go. I have been overwhelmed by how friendly and inclusive people are in HK, so enjoy!
