People always say that they're a sceptic or a pessimist. No. It's called being gutless. It takes courage to look for the good. It takes guts to try, even if that means failing.
It's easy to look for the negatives and ignore the positives. It's easy to say "fuck it" and stay exactly we are.
It's this fear of rejection and disappointment why we don't even try and give things a real shot. It's all these self-defence mechanisms which blocks out the pain instead of facing it. When a relationship starts breaking down, it's much easier to see things a lot worse than what they really are, so that we don't even bother.
