One that loved wisely but not too well

Othello:
I pray you, in your letters,
When you shall these unlucky deeds relate,
Speak of me as I am; nothing extenuate,
Nor set down aught in malice. Then must you speak
Of one that lov'd not wisely but too well;
Of one not easily jealous, but being wrought,
Perplex'd in the extreme. . . .
