what is the theme/ central message of htis poem?

Question

I PLAY’D with you ’mid cowslips blowing,
When I was six and you were four;
When garlands weaving, flower-balls throwing,
Were pleasures soon to please no more.
Through groves and meads, o’er grass and heather,
With little playmates, to and fro,
We wander’d hand in hand together;
But that was sixty years ago.

You grew a lovely roseate maiden,
And still our early love was strong;
Still with no care our days were laden,
They glided joyously along;
And I did love you very dearly,
How dearly words want power to show;
I thought your heart was touch’d as nearly;
But that was fifty years ago.

Then other lovers came around you,
Your beauty grew from year to year,
And many a splendid circle found you
The centre of its glittering sphere.
I saw you then, first vows forsaking,
On rank and wealth your hand bestow;
O, then I thought my heart was breaking!—
But that was forty years ago.

And I lived on, to wed another:
No cause she gave me to repine;
And when I heard you were a mother,
I did not wish the children mine.
My own young flock, in fair progression,
Made up a pleasant Christmas row:
My joy in them was past expression;
But that was thirty years ago.

You grew a matron plump and comely,
You dwelt in fashion’s brightest blaze;
My earthly lot was far more homely;
But I too had my festal days.
No merrier eyes have ever glisten’d
Around the hearth-stone’s wintry glow,
Than when my youngest child was christen’d;
But that was twenty years ago.

Time pass’d. My eldest girl was married,
And I am now a grandsire gray;
One pet of four years old I’ve carried
Among the wild-flower’d meads to play.
In our old fields of childish pleasure,
Where now, as then, the cowslips blow,
She fills her basket’s ample measure;
And that is not ten years ago.

But though first love’s impassion’d blindness
Has pass’d away in colder light,
I still have thought of you with kindness,
And shall do, till our last good-night.
The ever-rolling silent hours
Will bring a time we shall not know,
When our young days of gathering flowers
Will be an hundred years ago.

Answer 1

It's one man's homage to his first love. As they grew up, their paths split -- she evidently married for money which nearly broke his heart. He married someone else and found happiness and contentment in his family -- wife, children and grandchildren.
And he bears his first love no regrets. Whatta guy!

Answer 2

I think its about his First Love. and the message is that your First Love is someone you'll never forget.

Answer 3

Fond memories of his childhood and first love.
