Shakespeare's got the right idea.

"[Love] is to be all made of sighs and tears...

it is to be all made of faith and service...

it is to be all made of fantasy,

all made of passion and all made of wishes,

all adoration, duty, and observance,

all humbleness, all patience and impatience,

all purity, all trial, all observance."

~Silvius, As You Like It, Act 5 Scene 2

I want a love like that.
