Which line in this song from act ii, scene iii, of twelfth night illustrates that the song is about unrequited love?
clown:
song
come away, come away, death.
and in sad cypress let me be laid;
fly away, fly away, breath;
i am slain by a fair cruel maid.
my shroud of white, stuck all with yew,
o, prepare it!
my part of death no one so true
did share it.

not a flower, not a flower sweet,
on my black coffin let there be strown:
not a friend, not a friend greet
my poor corpse where my bones shall be thrown:
a thousand thousand sighs to save,
lay me, o, where
sad true lover never find my grave,
to weep there!

"I am slain by a fair cruel maid. "

Explanation:

The line "I am slain by a fair cruel maid" shows that the speaker feels he was killed by the rejection that a woman, in this case the cruel maid, has imposed on his love. That is, in this line the speaker shows that he was rejected, that his love was unrequited, so he feels that his beloved has killed him, since she does not love him and he believes, that living without this love is the same as dying.
