This was Hard-y

Between us now and here -
Two thrown together
Who are not won't to wear
Life's flushest feather -
Who see the scenes slide past,
The daytimes dimming fast,
Let there be truth at last,
Even if despair.

So thoroughly and long
Have you now known me,
So real in faith and strong
Have I now shown me,
That nothing needs disguise
Further in any wise,
Or asks or justifies
A guarded tongue.

Face unto face, then, say,
Eyes mine own meeting,
Is your heart far away,
Or with mine beating?
When false things are brought low,
And swift things have grown slow,
Feigning like froth shall go
Faith be for aye

This poem captures the essence of older love or love that has sweetened with age. 
It grapples with the objective that since they have been together for so long if '...your heart [is] far away or with mine beating..' meaning is the love still there or is it slowly running out like the time they have left on earth. 'We are not wont to wear life's flushest feather' meaning they are old, and withered, not flushed with youth and their 'daytimes dimming fast'. The second stanza refers to how the two have known each other for a really long and know each other so well that they don't have to guard what they say from one another. They are both confident in themselves and who they are. Hardy utilizes his own special writing formation and structure to remind one what they are reading about when the second rhyme kicks in. He also uses metaphor such as  'daytimes dimming fast' to simulate the fading and waning of their own lives. 'Feigning like froth shall go' simulates the ebbing of actual froth [product of churned water] and it just another reference to how they are going to die soon as they perceive it. 

I've studied this poem in extent. It is so groovy. 
o,
Faith be for aye.
