I’m Finnish and I’ve lived in Sweden, Scotland and Canada so far. I enjoyed myself in all of those places and my only reasons for leaving were studies or work. Next year I’m moving to Portugal to be closer to mine and my husband’s families and I’m expecting it to be yet another smooth transition. I think the key is to know the language, the good and the bad (it seems that you do), and to manage your expectations. Life there might not be at all what you expect so keep your goals flexible. At least that’s what I always did and it worked out nicely. Good luck!
I’m in a binational couple and we met and currently live in a 3rd country. We are relocating to another 3rd country next year and while we considered moving to either one of our home countries, we decided against it. A 3rd country is a neutral territory where we are both foreigners/immigrants/expats and I think that makes many things easier. In one of our home countries, one of us would be more dependent on the other (at least in the beginning) and that person would be the « foreigner « . I’m sure it’s possible to make it work but it’ll take some time and extra work. Wishing you the best of luck!
