Right, well with the origins of Valentine's day covered, it would be churlish not to get into at least some of the better bon mots and billets doux.
"A coward is incapable of exhibiting love; it is the prerogative of the brave." Mahatma Gandhi
"A kiss is a lovely trick designed by nature to stop speech when words become superfluous." Ingrid Bergman
"A lady of forty-seven who had been married twenty-seven years and has six children knows what love really is and once described it for me like this: 'Love is what you've been through with somebody.'" James Thurber

"I have found the paradox that if I love until it hurts, then there is no hurt, but only more love." Mother Teresa
"A loving heart is the beginning of all knowledge." Thomas Carlyle

His hat was old, his coat worn, his cloak was out at the elbows, the water passed through his shoes, - and the stars through his soul." Victor Hugo
"I was about half in love with her by the time we sat down.

Salinger (Holden Caulfield in The Catcher in the Rye)
And, girls, a little tip if anyone is being too persistent:
"I was nauseous and tingly all over. I was either in love or I had smallpox." Woody Allen
ps - can't have love poems without Pablo Neruda. This one is called "Your hands"
When your hands leap towards mine, love, what do they bring me in flight? Why did they stop at my lips, so suddenly, why do I know them, as if once before, I have touched them, as if, before being, they travelled my forehead, my waist?
Their smoothness came winging through time, over the sea and the smoke, over the Spring, and when you laid your hands on my chest I knew those wings of the gold doves, I knew that clay, and that colour of grain.
The years of my life have been roadways of searching, a climbing of stairs, a crossing of reefs. Trains hurled me onwards waters recalled me, on the surface of grapes it seemed that I touched you. Wood, of a sudden, made contact with you, the almond-tree summoned your hidden smoothness, until both your hands closed on my chest, like a pair of wings ending their flight.
