My H parents are both dead. His mother when he was 13 years and father when he was 18 years.

He has visited their grave twice recently whereas before he never went. I believe he is sorting the issues out in his head by visiting them where they are and although he can't speak to them it helps unmuddle his mind and come to terms with what he needs to.

Don't be too pesimistic about your H parents being dead. Where there's a will there's a way..........
