My wife chose a grave flanked by by two likely saints whom she loved and I guess she couldn't be happier. But that leaves me no way to be buried next to her. I told the kids if I don't remarry, to have me cremated and put in with mom. But I certainly expect to be buried elsewhere if I remarry.
As to visiting a grave site, there will never be a electronic alternative. The remains of a saintly person are first class relics. I know that my chest was continuously crushed anywhere but besides my wife Aimee. And although she is dead in this world, somehow being near her earthy remains gave me such peace and joy and contentment. It seems so odd that a man could only find joy sitting beside the grave of the the love of his life, but if I didn't have kids to care for, I might never have left her side.
I think the grave site belongs to the kids. They will live the longest with that hole in their life. Hopefully, I will remarry. but nobody can ever fill that hole in their hearts.
