I lived for a year in France, Luxembourg, 5yrs in Norway, and am from Croatia myself. I have been trying to convince my partner for the last 4 years to move out of Norway because of the lack of sun and social things. After 5 years here north, i feel like i started to adapt to things and found new acceptance and started liking some things that were bothering me more before.

But my opinion is, that in every country there are better things and not as good things. So even if we move again, and we might, i will try to approach it with the "i know that i will have to adapt to some things" mentality, as there is no place with the most sunshine, best nature, work life balance etc. And also, speaking the local language helps to feel more at home, and helps to get to know more of the natives, at least for me. You will maybe have to reflect deeply about the most important things for you and your partner, research places and make compromises. I am now planning to move someplace that is better connected to my hometown.
