"I don't know. If being in love only made people more lonely, why would everyone want it so much?" "Because of the illusion. You fall in love, it's intoxicating, and for a little while you feel like you've actually become one with the other person. Merged souls, and so on etc etc. You think you'll never be lonely again. Only it doesn't last and soon you realise you can only get so close, and you end up brutally disappointed, more alone than ever, because the illusion-the hope you'd held on to all those years-has been shattered".
