What does the Robert Browning's "Parting at Morning" want to say? What's it's meaning? And who is the speaker in this poem?

'Parting at Morning' is the companion poem to 'Meeting at
Night' which details a lovers' tryst. 'Parting at Morning' is about the two lovers going
their separate ways the next day. There has been debate about who the narrator of the
poem is but Browning suggested that it is the male lover
speaking.

The poem suggests the fleeting nature of love
which makes the parting of the lovers inevitable as he has to return to 'the world of
men.' Love is like the night itself; over quickly to be replaced by the perhaps harsher
reality of the day.
