Stephen Vizinczey said this quote

We think of ourselves as failures, rather than renounce our belief in the possibility of perfection. We hang on to the hope of eternal love by denying even its temporary validity. It´s less painful to think 'I'm shallow', 'She's self centred', 'We couldn't communicate', 'It was all just physical', than to accept the simple fact that love is a passing sensation, for reasons beyond our control and even beyond our personalities. But who can reassure himself with his own rationalizations? No argument can fill the void of a dead feeling -- that reminder of the ultimate void, our final inconstancy. We're untrue even to life.
