We should measure affection, not like youngsters by the ardor of its passion, but by its strength and constancy.

One man; two loves. No good ever comes of that.

Only the person who has faith in himself is able to be faithful to others.

To be capable of steady friendship or lasting love, are the two greatest proofs, not only of goodness of heart, but of strength of mind.

It is as foolish to make experiments upon the constancy of a friend, as upon the chastity of a wife.

Constancy in love is a perpetual inconstancy, which makes the heart attach itself successively to all the qualities of the person we love, giving preference now to one and presently to another.

There are two sorts of constancy in love; the one comes from the constant discovery in our beloved of new grounds for love, and the other comes from making it a point of honour to be constant.

The violence we do to ourselves in order to remain faithful to the one we love is hardly better than an act of infidelity.

The heart grows weary after a little Of what it loved for a little while.

He wears his faith but as the fashion of his hat.
