We see our daughter (mid 20's) on average 3-4 times a month. Every 7-10 days. She lives 20 miles from us (in another town,) with her boyfriend. 3 out of 4 times we see her, it will be us going to her town.
She is a very busy career woman, and we have more free time than her, so we don't really mind. We meet her for lunch 2 or 3 times a month (we go to meet her at her workplace, and pop into the Costa or Maccy D's near her office.) Or we will have a meal out with her (and sometimes with her B/F too.)
She and her B/F come to ours about once every 5-6 weeks.
I would find it very hard if she moved away, like multiple 100's of miles, and we rarely saw her. I know a few people whose offspring have moved away 200 to 400 miles, and they see them maybe every 5-6 months; a week or 2 in the summer, and Christmas!
I also know several people whose offspring live abroad. One woman has had all three of her children (one daughter and two sons,) move to different countries. All three! Two of them really far away.... Australia, and Chile!!!
Not judging or anything, and I know people are entitled to do what they want (when they're adults,) but I would be really sad and upset if my daughter moved abroad. Especially 8 to 10 thousand miles away! (I wouldn't tell her I was upset, but I would be........)
I missed her enough when she was at uni, and that was only 100 miles away, and she came home every 4 or 5 weeks, (and spent all the uni holidays at home!)
