Hi,
My partner is from Bergen and I lived there 2001-2004. It is an amazingly beautiful place, but it can be quite a culture shock. Our situations are different though, my partner had a job and all his friends he'd had since pre school and his family and of course he knew the language, whereas I had to find my place and learn the language, and as I moved to be with him, my aim was to integrate and continue with my nursing career.
If you're moving with your husbands company I'm guessing they will fix all the practicalities of visa, work permit etc and fix schools and daycare etc. Schooling, daycare (barnehage) health are all excellent and the people are well taken care of by the state (subsidised childcare, free healthcare (hospital, not GP), great maternity/paternity benefits) as well as a generally forward thinking country where equal rights mean that women can progress as much as men, pay is equal, and there is less divide between rich and poor.
Of course it is not perfect, nowhere is, the weather is shocking, people walk to work 300 days per year is full rain gear which really got to me. They are not tolerant of immigrants, specifically 'non western' immigrants. Cost of living is high (£10 for a pint for example) but wages are high, and the measures the government have in place for families, i.e. subsidised childcare, mean that disposable income for us was way higher than where we are now (Sydney, comparable, because cost of living, property/rent is similar, but huge daycare fees mean that we have no disposable income).
I would go for it, you and your husband have the same cultural benchmarks, and if you don't like it you can come back. I struggled, but it took 4 years to get my education recognised and my partner just didn't get it when I thought things were odd, such as shops closed on sundays, the whole place shutting down for summer etc.
We have the dilemma of where to move back to, England or Norway, I like the idea of my children having the opportunity to become prime minister if they so wish, as I feel that that is possible in Norway, there is no obvious class divide so everyone has a chance and I like that, I also have 2 girls and they would not be held back in Norway for being female or having children etc, but I have a problem with the distaste for foreigners and the endless bureaucracy. To be honest, I think it is a marmite kind of a place, you either love it or you hate it, and you'll never know which unless you try :) Good luck!
