My husband lived in Bogata, Colombia for 9 months during our marriage. He flew home about once a month for a few days, or I went there. It was fine, he had been trvelling a lot with work prior to that anyway. Since we knew it was temporary and I was working full time it wasn’t terrible, but I much prefer he not live apart from me. But, just three weeks ago he moved to where we will be living and I am still back in the old city trying to get ready to sell our house. I probably won’t see him for a month.
Many years ago my husband moved to America for college, his sister lived here, but his brother was still in Mexico with his parents. I think it was tough on his parents not having their children near, but they handled it ok. His mom would visit sometimes for a couple of months. When he and I married his sister and her husband shortly after moved to the Dominican Republic. She came to visit a couple times a year, we went there once during the 4 years she lived there.
My sister and I have lived in different states since she was 14 and I was 16.
I haven’t lived in the same state as my parents since I left for college.
I know you said other side of the world, so I am not sure if any of these really qualify. Sone of them require a plane ride and some are in different countries.
A friend of ours has lived in various parts of Asia for he job. Her husband never permanently moved over there with her, but he would go sometimes for a month at a time. Almost her entire family lives very near to each other in the same state. She has 5 or 6 siblings, I can’t remember exactly how many. She also has a daughter, and during that time grand kids were born.
Pretty much it is normal to me for people to live in various places and move around.
