i love that poem.... i guess what your question is pertaining to is the risk associated with falling in love with someone, and one of the major risks is losing them and the associated pain...that made me think about the following poem which has been posted before...i find it very moving.....
Time does not bring relief
Time does not bring relief; you all have lied
Who told me time would ease me of my pain!
I miss him in the weeping of the rain;
I want him at the shrinking of the tide;
The old snows melt from every mountain-side,
And last year's leaves are smoke in every lane;
But last year's bitter loving must remain
Heaped on my heart, and my old thoughts abide.
There are a hundred places where I fear
To go - so with his memory they brim.
And entering with relief some quiet place
Where never fell his foot or shone his face
I say, 'There is no memory of him here!'
And so stand stricken, so remembering him.
Edna St Vincent Millay (1892 -1950)
