Neil,
As one electrical guy to another, DON'T devalue yourself!! If you think she is so happy in this idealic life you've painted here, why do you you think she started looking overseas for a man such as yourself? I take it you have told her everything about yourself and your situation? Well if you have she has made her choice....YOU!!
There was obviously something missing in her life, that was more important to her, than the life she is currently living... You are filling that missing critera, and she's happy that you are too...
These Chinese ladies are not silly or stupid Neil, they know what they want in there life. You can, (and sounds like you are) give this lady real LOVE, it's probably something she's never experienced in her adult life, and once found, she will be very reluctant to give away or abandon.
Sure you have to work things out between you, to find the best way of taking that new life forward, but believe me, if she loves you as much as it seems. She will do anything and everything to make that new life work for both of you. You need a short and a long term plan, try and be realistic when your making those plans between you. Remember, she will be expecting you to fulfil those plans once they have been argreed!!
This trip, just enjoy yourself with your lady, and try and get to know her, as much as you can. Don't just see her outward beauty, look far beyound that. Also recognise any not so good points, as well as the numerous good ones.
I'm not going to tell you how to suck eggs, i'm sure you'll do just fine working things out while your there.
Oh, one last thing, ....They sure do need GOOD Sparky's there mate, .....that is one thing i DO know about!! haha!!
David......
