I did this with my husband.
He is American, I'm Australian.
It was a nightmare,so many issues...we were very much in love,in the end he was able to come and live in Australia....but that took a year, and it was such a hard time.
The phone calls 25 yrs ago were a lot of money, and I would write to him maybe 6-7 letters a day!!! Nearly every day.
In the end, years later he was too homesick, and he had to go back home.
I would not leave Australia for anything or anyone.
So..... our son and I stayed back.
