Dissapointed or expecting?

Do you have people around you whom you know you can't and shouldn't trust, yet you keep them close to you?! Cos I do!
It's so very hard being betrayed by someone close to you. You think of it, think of how you would react and still when it happens you are drown into the unknown. As if you're left without air, and you need it as if never before, as if the breath you need would save your life...
Are there people who are dead to us long before thier physial death? Are there people we wish would disappear and never come again into out life? Is our hate so strong or is it their stupidity and immorality?
