Amitié and donner and mourir and offrir

Offrir l'amitié à qui veut l'amour, c'est donner du pain à qui meurt de soif.

To offer friendship to someone who wants love is like giving food to someone who is dying of thirst.

Or

Nothing is crueler than unrequited love.

Literal translation:
To offer the friendship to who wants the love, it is to give some bread to who dies of thirst.
