Guess it depends on the day really. I'm not married to a British man, we chose to live here, it will be 5 years in January. There are great days like when we go to an awesome show, or the flower market, rainy fall weekends, or access to amazing [insert anything here] and I can't think of living anywhere else. Then there are the days when the political rhetoric gets you down, you have a bad day at work, the neighbors are driving you crazy, or nothing seems to work. Those are the days when I start looking at property back in the US or Sweden, or jobs in the EU, or wishing to be somewhere where we know all the rules.
I say I am from my hometown, which is true, I was born there and its small enough where my family name matters. But I didn't grow up there and moved around the US - this was my seventh move across the continent. I didn't go to high school in the same town where I went to junior high, which wasn't the same town as where I went to elementary school. Not even the same states. More often than not now when we go back to the US we tend to go to California or Florida, and not often to my home state, which is none of the three I went to school in. Im not close to my siblings, my family is very small and dying off, and I don't have any close friends left from high school or college. It doesn't really bother me, I learned a long time ago how to be independent and how to say goodbye.
Thankfully my partner is a wonderful guy who, although he grew up in a small town, couldn't wait to get out of there and never look back. He has loads of friends and small family still there, and its fun to go visit, but to be there for longer periods of time we would need our own space.
So, we have quite a bit of wanderlust and eventually want to have multiple homes to take advantage of everything. Some days I forget where something is kept here because I am remembering where it was kept in a former house in the US. Or, where are my ice skates (pretty sure they are in Sweden right now). He has boxes of vinyl records in the UK, Sweden, and at my parent's house, which is becoming something of a running joke. Someday we will see them again, but probably not here.
