我曾经爱过你；

爱情，也许，

在我的心灵里还没有完全消失；

但愿它不会再去打扰你；

我也不想再使你难过悲伤。

我曾经默默无语地，毫无指望的爱过你，

我既忍着羞怯，又忍受着妒忌的折磨；

我曾经那样真诚，那样温柔的爱过你

但愿上帝保佑你，另一个人也会像我一样爱你。

Alexander Sergeyevich Pushkin  

I loved you; and perhaps I love you still,

The flame, perhaps, is not extinguished; yet

It burns so quietly within my soul,

No longer should you feel distressed by it.

Silently and hopelessly I loved you,

At times too jealous and at times too shy.

God grant you find another who will love you

As tenderly and truthfully as I.

Another translation by  Dr. Daniel Feeback:

I loved you once; perhaps I should exclaim,
My love still lingers deep within my core.
But I do not want to cause you any pain,
So grieve thee not for me a moment more.

Silently and hopelessly I loved you,
Tormented, I was too jealous and too shy.
May God provide another who will love you,
Just as gently and as fervently as I.

A favorite for guest translations, here's the original Russian along with a mostly literal translation:

I loved you:  yet the love, maybe,
Has not extinguished in my heart;
But hence may not it trouble thee;
I do not want to make you sad.
I loved you hopelessly and mutely,
Now with shyness, now with jealousy being vexed;
I loved you so sincerely, so fondly,
Likewise may someone love you next.

The original Pushkin's poem:
Я вас любил: любовь еще, быть может,
В душе моей угасла не совсем;
Но пусть она вас больше не тревожит;
Я не хочу печалить вас ничем.
Я вас любил безмолвно, безнадежно,
То робостью, то ревностью томим;
Я вас любил так искренно, так нежно,
Как дай вам бог любимой быть другим.
