Why is the measure of Love loss?

Sorry for not posting properly, my camera is completely wrecked.

To make up for it, a beautiful passage from a beautiful book:

‘You were careful not to say those words that soon became our private altar. I had said them many times before, dropping them into coins like a wishing well, hoping they would make me come true. I had said them many times before, but not to you. I had given them as forget-me-nots to girls who should have known better. I had used them as bullets and barter. I don’t like to think of myself as an insincere person but if I say I love you and I don’t mean it – then what else am I? Will I cherish you? Will I adore you, make way for you, make myself better for you, look at you and always see you, tell you the truth? And what is love is not those things? Then what?'
