Of course.. I already am. I moved here seven months ago to stay permanently. It's a little different though, I moved to get married and live with my wife. That's different that already having an American family (besides parents/siblings/etc) and moving or studying abroad. I miss a lot of my friends and family back in the States but we still manage to keep in touch and hopefully I'll earn enough money to fly back and stay for a month or so every few years. You do feel out of the loop, though - it's even more difficult to stay informed on news and stuff back in the States. But you enter a whole new circle with different issues and people as well so it can be refreshing.
Your story would be romantic, if it didn't end in Cranbourne
