can't someone amazing just enter my life and fall in love with me? just a thought!

How do you prevent yourself from breaking your own heart? Is it possible to love and hate someone at the same time? Why the pain? It's all my fault anyway....this is what happens when you believe in something....that will never happen. Blah blah blah...time to hang my heart back up and lock the key. Would that make up for the pain? or just make it hurt worse?
