When you move, make sure that it’s somewhere near to facilities that you will need as you get older. Doctor surgeries, hospitals, shops etc. You do not have to live near your adult children to maintain your relationships with them or your grandchildren. Discuss it with them and see whether they have any strong views. A friend of mine moved to be nearer her daughter and her family at the daughter’s request. Five years and mammoth stints of (free) babysitting later, the daughter and her family moved to another part of the country altogether. My friend was then stuck without a support network and couldn’t afford to move again. You need to think ahead and plan for your own comfort and health too. Will your family take you in when you are finding it difficult to look after yourself? If that’s not going to happen or you haven’t discussed it yet, factor that in to your choices before you move.
I moved to a rural area 4 hours away from my grown up children i felt guilty but needed to do it at that part of my life ..loved their visits made it special ..and sometimes in school hols we'd meet half way at the services and I'd take my grandkids back with me ..worked really well
