Why do I set myself up for disappointment?

I am kicking myself in the butt for trusting someone to abide by an agreement that they made and then not sticking by it. I will not go into specifics. Let's just say it's hard to have faith in mankind / womankind when you can't even trust a friend to keep there word to you. It's my fault, I should have known better I suppose. I try to help people out and get trampled on in the stampede of excuses for selfishness and narcissism.
