Analysis of An Ending

I will go my ways from the city, and then, maybe,
My heart shall forget one woman's voice, and her lips;
I will arise, and set my face to the sea,
Among stranger-folk and in the wandering ships.

The world is great, and the bounds of it who shall set?
It may be I shall find, somewhere in the world I shall find,
A land that my feet may abide in; then I shall forget
The woman I loved, and the years that are left behind.

But, if the ends of the world are not wide enough
To out-weary my heart, and to find for my heart some fold,
I will go back to the city, and her I love,
And look on her face, and remember the days of old.
