My first ‘emigrant’ went backpacking in Australia 22 years ago. She was offered sponsorship and a good job, and remained there. Three more of my five children followed her, though one has since divorced, and returned home with her two DC.
Yes, I miss them all a lot, especially now that they have children. They have much better prospects over there, though, and a wonderful life. I normally visit every couple of years, and stay for several months. My visit this year, for the birth of my new GS was put on hold, of course. I get regular FaceTimes with all the various families, and my little GD, who is three, chats with me while she eats her breakfast, or has her bath, and I often read her a bedtime story.
With goodwill on all sides relationships can continue, even though they are not the hands-on ones we would like. I wouldn’t expect my family to plan their lives around me, but we do our best to forge a new kind of family life. It works pretty well, and I’m sure that you will adapt, given time.
