Joyfully, geographical separation is totally different to estrangement!! A couple of years ago my DIL decided suddenly to cut me off. After looking after my grandson four days a week (taking him to tennis, soccer, swimming, kindy, etc and having him for sleepovers two nights a week) and my granddaughter two days a week, I was allowed no contact. This went on for several months and then with the help of negotiations through my partner and a voice of reason from my son, things improved and I was allowed to see them once a fortnight (not the same but better than being completely cut off). Now they have moved to England (I live in Australia) and I must say that the feeling is totally different. Although I will not be able to visit them because of health issues, I can FaceTime and Skype and I live in the hope that when they are older I can send them a plane ticket to come back and visit. I am sad, but not completely devastated as I was during the estrangement. So no, imagining the kids are simply halfway around the world when you are in fact estranged from them is not useful. And estrangement is far worse than bereavement. My heart goes out to all of you out there who are experiencing estrangement from your grandkids!!! From my experience there is no worse pain and anguish!!!
