Mr Hat's advice (as usual) is right on the money.
My wife and I treated it as a big adventure and there were some lonely times for me up north as I got established before dragging her along, but somehow we made it work and are still together.
Mrs RR likes the fact I'm not so grumpy anymore and actually like fronting up for work. When I suggest I should pack in flying for a living and go back to earning more money in my old career, she tells me to forget it as she'd rather be poor but with a happy RR than better off but with a grumpy RR! What a gal.
So there's part of your answer. You'll never never know if you never never (give it a) go.
