Basically, this. We can afford to live in places that don’t give us such a high income by now, and we simply like them better. More time to enjoy ourselves, a culture that’s more aligned with our values, and a place we have simply come to love and feel at home every time we’ve visited. So we’re not primarily looking for economic opportunity now, we’re looking for quality of life… and the US is much, much better at economic opportunity than it is at quality of life.
I want to add my reassurance: if he’s not in a place to be thinking of your future together, you need to be thinking of your future alone. Kudos for recognizing that – it’s one of the hardest things to make yourself do, especially if the relationship otherwise feels as if it’s going well at the time. But if you’re strong enough to have made this decision, you’re strong enough to get through the painful time that follows.
And when you’ve done that, you’ll be in exactly the place where you actually want to live, without having to compromise on it.
Good luck!
