TrishaJ I apologise that my original comment unfortunately detracted the thread from your genuine request for constructive help and advice.
As your son has been willing to let you look after your GC for quite a long time then it does seem that the move has triggered whatever he is feeling now. His comments seem oddly extreme within the context of babysitting and holidays together! If you look back over that time with real honesty, I wonder if you can identify unspoken tensions, irritations, walking on eggshells type stuff that was maybe ignored, swept aside, swept under the carpet, but which have come to the fore in his mind due to this move.
|The other possibility is that all of his comments were made in real anger that you had moved away and were irrational but now said, have to be dealt with
As you are afraid of more abuse. I would write/email very unemotionally saying that you are unclear what he means but are happy to listen and discuss; that , even if you have made mistakes from his perspective, you love them all very much and would hope that any problems can be sorted; that you hope that very soon you can all enjoy the pleasures of Devon together as a family. Tell him that you really hope to hear from him very soon to arrange to meet and discuss the issues, repeat that you are happy to listen and try to understand.
If and when you do meet, I would let him say all he wants to say without interruption (otherwise it is more likely to just turn into an argument). When he has finished, you either reply to the points with your own perspective or if unable to do that you tell him you need time to think over his points and would like to chat again ...and arrange another time when he listens to you without interruption
This all sounds pretty convoluted but might help to take some of the emotion out and get to the root of the issues as he perceives them.
This is hard and sad for you and I hope that you can get it sorted
