No love is puré

Pardon. No love is pure (the automatic correction tricked me again). Love is the dirtiest thing of all - just look at the fluids going in and out. Makes you more discriminating than ever - there's only one person right for you (yes, I'm assuming you're monogamous). It makes you more selfish - you want him / her just for you. Except when you're mad at him - usually for an insane reason - and then you just want to kill him.
