What is Thomas Hardy's "After a Journey" about?

I feel that Hardy is saying in 'wrought division' that all married couples have arguments. As and when his wife dies he says, 'Dear. to vanish from me,' so she is still 'Dear' to him. And at the end he still remembers fondly her memory and wants her to 'bring me here again!/I am just the same as when/Our days were a joy, and our paths through flowers.' So, yes, Hardy moves on from Emma but never away from her. This is terribly sad when he says, 'When you were all aglow,/And not the thin ghost that I now frailly follow!' Poor Hardy although I always feel that as he grew older his poetry grew from good to outstanding, as this one is.
