My parents chose to move 6000 miles away when my children were 3 and 4. My sister was pregnant with her first child. They wanted a warm climate. They took my grandma with them. So parents and only grandparent moved away. We visited them many times over the first 6 or 7 years. Of course it was expensive but we sacrificed things to keep family ties going. They’ve been there 20 years now. Anyway, we havent visited for the last 12 years. Due to expense and children’s education etc etc. I’ve bent over backwards trying to keep relationships going from afar. Encouraging my kids to call and email. My parents haven’t been back to visit us in UK for 19 years. My mum died a few months ago and dad is now struggling on his own. He doesn’t want to move back. His health is failing. My other sister (there’s 3 of us) lives with him as 6 years ago she went through a divorce and has lived with my parents since. She has mental health issues and various ailments. I still carry resentment that they moved away. If they walked passed their grandchildren in the street they wouldn’t recognise them. I’ve encouraged contact over the years with minimal reciprocal effort. My dad is asking for help. My sister who lives with him is ill and can’t hope. Suggestions please?
