It is not an easy decision to make. My friend had a similar problem and just as she was about to consider seriously, a move to her only son and two grandchildren, he lost his job and has now moved abroad. Needless to say, she has decided to stay put!
Our 14 grandchildren live in various parts of the country and 2 live abroad, so the decision to stay where we are is easy. We can't be near all of them!
Good luck and all the best whatever you decide.
Is it me or am I getting mixed messages
