Question

anyone can explain that :
"she is too fair, too wise, wisely too fair.
to merit bliss by making me despair.
she hath forsworn to love in that vow do i live dead that live to tell it now"

sorry, i am newbie,

Answer 1

Here is my interpretation:

Stanza 1: It's a play on words; she is beautiful (fair) and wise, and that wisdom reflects in her behavior of fairness (free of injustice - related to stanza 2).
Stanza 2: She is just in that she does not accept my love without reciprocating.
Stanza 3: She won't declare her love to me because it isn't true, but I wish to declare it for her and seem to die because of it.
