You never really know somebody.
They can get you hopes up... only to let you down. I have been let down many times by the people closest to me. But when someone you know hurts you, when you have trusted this person, and let them in, being hurt by them just hurts that much more.

Moving on is the hardest part, especially when there is no longer someone to talk too.

Its hard to explain it but from where I stand, trust can be a lie and you never can really know somebody.
