Answer:
"I am slain by a fair cruel maid. "
Step-by-step 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.
