If one of two lovers is loyal, and the other jealous and false, how may their friendship last, for Love is slain! But sweetly and discreetly love passes from person to person, from heart to heart, or it is nothing worth. For what the lover would, that would the beloved; what she would ask of him that should he go before to grant. Without accord such as this, love is but a bond and a constraint. For above all things Love means sweetness, and truth, and measure.
