It was all love on my side, and all good comradeship and friendship on hers. When we parted she was a free woman, but I could never again be a free man. – Sir Arthur Conan Doyle

Girls, like men, want to be petted, pitied, and made much of, when they are diffident, in low spirits, or in unrequited love. These are services which the weak cannot render to the strong and which the strong will not render to the weak, except when there is also a difference of sex. – George Bernard Shaw

I do not now begin,–I still adore
Her whom I early cherishd in my breast;
Then once again with prudence dispossessd,
And to whose heart Im driven back once more.
The love of Petrarch, that all-glorious love,
Was unrequited, and, alas, full sad… – Johann von Goethe
