Relationships of all kinds are like sand held in your hand. Held loosely, with an open hand, the sand remains where it is. The minute you close your hand and squeeze tightly to hold on, the sand trickles through your fingers. You may hold on to some of it, but most will be spilled. A relationship is like that. Held loosely, with respect and freedom for the other person, it is likely to remain intact. But hold too tightly, too possessively, and the relationship slips away and is lost. -Mark Victor Hansen

There is no greater glory than love, nor any greater punishment than jealousy. -Lope de Vega

No true love there can be without Its dread penalty -jealousy. -Lord Lytton

It is not love that is blind, but jealousy. -Lawrence Durrell

Plain women are always jealous of their husbands. Beautiful women never are. They are always so occupied with being jealous of other women's husbands. -Oscar Wilde

Do not be afraid of showing your affection. Be warm and tender, thoughtful and affectionate. Men are more helped by sympathy, than by service; love is more than money, and a kind word will give more pleasure than a present. -Sir John Lubbock

A slight touch of friendly malice and amusement towards those we love keeps our affections for them from turning flat. -Logan P. Smith

Caresses, expressions of one sort or another, are necessary to the life of the affections as leaves are to the life of a tree. If they are wholly restrained, love will die at the roots. -Nathaniel Hawthorne

Affection, like melancholy, magnifies trifles; but the magnifying of the one is like looking through a telescope at heavenly objects; that of the other, like enlarging monsters with a microscope. -Leigh Hunt

The moment we indulge our affections, the earth is metamorphosed, there is no winter and no night; all tragedies, all ennuis, vanish, all duties even. -Ralph Waldo Emerson

Talk not of wasted affection; affection never was wasted. -Henry Wadsworth Longfellow

Love is the master key that opens the gates of happiness. -Oliver Wendell Holmes
