In my search, I found that epitaph done in the first person singular, "She will not return to me, but I will go to her," but not as posted here. I will take a guess at Elizabeth Edwards?
It sort of reminded me of the epitaphs on the single spire that marks the graves of my great-grandparents. On one side is "Come Wife, Come," inscribed when Joseph Eli Huntt died in 1897. On the other side is "Husband, I Come," inscribed then or when wife Laura died in 1914.
That said, I did find some photos of gravestones with really funny (and some filthy) epitaphs:
DAMN, IT'S DARK DOWN HERE!
Here Lies
An Atheist
All Dressed Up
And No Place
To Go
LOVING FATHER

OCCASIONAL HUSBAND
JOKE'S OVER,
