I would not say that I regret moving here, but, it was A HECK OF A LOT HARDER than I thought it would be. In several very unexpected ways.
...
Moving country *in mid-career, during a bad economy* and expecting everything to just snap into place... was rather naive of me.
I feel much the same way.
I don't regret having moved to Scotland. This is where my husband needed to be, for now, and I don't regret anything that lets us be a family.
I think it's fair to say that I regret the necessity of moving. That is, I think he and I both wish circumstances had been different, so that he could have moved to the U.S. instead (which had sort of been our original plan).
For me, though, aside from the economic/career stuff, the biggest problem has been that
I miss
my family. So I can really sympathize with your wife. The problem with any international couple, though, is that no matter where you settle, someone's missing something. Their friends, their family, their favorite beer...whatever. Someone always has to give something up.
So, again, aside from the economic/career considerations, the only thing I would recommend that you be aware of is your own relationships with your family/friends. I'm not saying you shouldn't move, or anything like that. Just be aware that, if you're close to them, it's probably going to be harder than you think to be away from them. Which I'm sure your wife would confirm.
