Aw cjat, wish I could help. That's going to be a tough one going from BC to AL. Too bad it wasn't the other way round. Especially since the family, friends, everyone is in BC.
We did that as a family, and suppose you have to do what you have to do. If you can use it as a stepping stone, financially, and then return later perhaps. The thing is, it's a long haul and have to make the transition to live away somewhere that you may prefer not to be. I couldn't wait until I finished school and able to move back to BC again, where all my family lives again now also.
Some people go off to camp to work to make good money. It's a sacrifice one makes to get ahead in the world. If you're ok with getting into that mindframe and going for it, it's good. If all you can do is pine away comparing daily what you left, then it's not going to be great.
The scenery of the two provinces is so different, and BC being so beautiful would be tough to leave. But lots of beautiful places in Alberta also! .. just no ocean.
It would probably be easier financially to live in Alberta. I think realistically, your lifestyle will change, just with the climate change alone. Don't know where you'd like to live, but lots of great places, as well as lots of not.
If you both felt like giving it a try, even if it's a sacrifice you make for a few years, and return home again, it should work. The only downside is .. you mind end up liking it, make new friends .. and never want to come back.
