This is a post where I fear I may say too much, so I am going to attempt to be generic and simply approach an expat issue that I imagine a lot of spousal immigrants have experienced, and that I (perhaps naively) did not think I would face, in a way that focuses on resolution.
When you leave your home, your family, your friends, and your country for love, it's safe to say that you probably didn't do it lightly. You have thought through what and why you are leaving; you are confident and exuberant about the love you feel; you have made both practical and more emotional preparations for your departure. Your investment in your new home and life is enormous. And because of that change, I imagine most of us who emigrate (quite rightly and necessarily) don't think twice after making the decision itself - not through lack of consideration but because of conviction and happiness, and because of the need for momentum to get through the immigration journey.
Whether you fell in love for the first time, or for 'real' for the first time, I suppose you always imagine that you are invincible. Your confidence in a relationship so fitting, so crazily simple and yet so unimaginably complex, skyrockets. In this particular situation, it's also important to invest and to believe, whether consciously or otherwise, because of that being the [main] reason for such a life-changing move. Of course you give it your all, because no one else would make you want to move countries and, conversely, because you are moving countries, you give it your all.
So what happens, one, two, three, ten years down the line, when an event shakes your relationship in a way that makes you wonder if you need to adjust your viewpoint? When the anchor that keeps you on these new shores seemingly loosens a little? Having psychological distance between you and the person who is not only your closest companion emotionally, but quite literally the closest person at all, in a country that is still not fully your home - what then?
Being so removed from long term friends; from family; hell, from what's just normal for you means that minor issues, like navigating supermarkets and the inability of an entire state to indicate when making a turn, can cause exaggerated frustration and sometimes misunderstanding. Major issues can trigger severe loneliness, depression, and even agony. But I don't think being far away from home should actually make a significant difference when it comes to dealing with the latter, believe it or not.
My advice is this: realise that you are the same person as before, and that you are capable of finding solutions regardless of your location. Take a practical, pro-active approach. Speak to people. Speak to friends. Friends in your new home that you can trust. Friends back home-home who know you. Parents if you can. Find solace and strength in their encouragement. And take that to your partner, who you moved for, who you wanted to be with above all else, and remind both them and yourself of that. Trust your partner. Because it's actually not that different to having relationship difficulties at home (even though you may feel a greater sense of displacement than you might otherwise have): such difficulties hurt, and you need to work through them, and you need to find common ground - like any couple, anywhere. Don't let being abroad overwhelm you. You are here because you choose to be. Keep making that choice, and move forward. Close the distance.
I never thought that what would take me out was what was hiding down below.
Lost the battle; win the war;
Bringing my sinking ship back to the shore.
... There's a time and a place to die, but this ain't it.
If there's a future, we want it.
