Its a wonderful poem by John Clare...
I loved thee, though I told thee not,
Right earlily and long,
Thou wert my joy in every spot,
My theme in every song.
And when I saw a stranger face
Where beauty held the claim,
I gave it like a secret grace
The being of thy name.
And all the charms of face or voice
Which I in others see
Are but the recollected choice
Of what I felt for thee.
Could this be the same secret Christina Rossetti had?
I tell my secret? No indeed, not I:
Perhaps some day, who knows?
But not today; it froze, and blows, and snows,
And you're too curious: fie!
You want to hear it? well:
Only, my secret's mine, and I won't tell.
