Analysis of The After-Glow

Suspicion's playful counterfeit
Begot your question strange:
The only thing that I forget
Is that there's any change.
Did that long blight which fell on you
My zeal of heart assuage?
Less willing shall I watch you through
The milder illness, age?
To my monopoly first blind
When risks no longer live,
And careless of the hand so kind
That has no more to give,
Shall I forget Spring like a tree,
Nor boast, ‘Her honied cup
Of beauty to his lips save me
No man has lifted up!’
Mine are not memories that come
Of joys that could not last:
They are; and you, Dear, are the sum
Of all your lovely past.
Yet if, with all this conscious weal,
I still should covet more,
The joy behind me shall reveal
The joy that waits before:
I'll mind from sickness how to life
You came, by tardy stealth,
Till, one spring day, I clasp'd my wife
Abloom with blandest health.
