Your love hath been, nor long ago,
A fountain at my fond heart's door,
Whose only business was to flow;
And flow it did; not taking heed
Of its own bounty, or my need.
What happy moments did I count!
Blest was I then all bliss above!
Now, for that consecrated fount
Of murmuring, sparkling, living love,
What have I? Shall I dare to tell?
A comfortless and hidden well.
A well of love--it may be deep--
I trust it is,--and never dry:
What matter? If the waters sleep
In silence and obscurity.
--Such change, and at the very door
The choppy phrases interspersed with dashes suggest choking emotions. This well of deep love will never be dry and his feelings won’t go away —  they will just stay hidden and compressed at the bottom of his heart.
