So sorry for all your unhappiness.It sounds like the support thread for estranged grandparents is a really good idea.
Just a thought. Might it help to write a letter to the mother of your grandchild -acknowledging that there have been difficulties - but giving her some credit for any good things you might be able to think of! and explaining that you will continue to be interested in the welfare of the child whatever has happened between her and your son. And that you would appreciate some regular news, and to be able to send presents even if visiting would be difficult at the present time? Even if she does not answer it, you will have said what you wanted to say.
Years ago,I had a very difficult mother in law, of whom my now ex husband said prior to our marriage that the more he liked a girl, the more his mother hated her. It was clear from the start that I was never going to be good enough - as a result of which, when she chose to move to the other side of the world after her own divorce, I did not feel inclined to make sacrifices to go over to see her frequently! However, in time things improved, and when her son and I divorced after many years, she sent me a lovely, totally uncritical letter saying many nice things and that she thought I had been a very good mother. Don't give up.
