Love is when he lets her have her girlfriends over and he doesn't leave the room. Love is when she lets him have his guy friends over and doesn't leave the room. Love is when you stay by their side until the very end. Love is doing something you don't like but you enjoy it anyway because you're doing it together. Love is never without fights, or else it wouldn't be real. Love is not saying "I love you" after two days of dating. It is not holding hands when you walk and it is not kissing every chance you get. Love needs to blossom, and the only time when you can truly say "I love you" is when you're engaged.
Love is a force of nature. However much we may want to, we can not command, demand, or disappear love, any more than we can command the moon and the stars and the wind and the rain to come and go according to our whims. We may have some limited ability to change the weather, but we do so at the risk of upsetting an ecological balance we don't fully understand. Similarly, we can stage a seduction or mount a courtship, but the result is more likely to be infatuation, or two illusions dancing together, than love.
