Can I trust you with my heart

If we're all lonely people in this world looking to love and be loved, then why is it so hard to find someone you can trust with your heart? Is this just a world full of jaded people who really believe it's better to hurt that be hurt? It seems that every time I find someone who I like enough to let into my heart, they either pull away or hurt me. I'm fighting like hell to keep from being jaded and I'm trying to take every blow as an opportunity to grow stronger. But when it comes down to it, I'm standing in a hole clawing at the dirt to climb out and though I can see the blue skies above, sometimes I just get tired and want to give up.
