It looks to me that you have some kind of mental block over judging people or your too quick to trust. I used to have the same problem. In American society its frowned upon to judge people but the truth is if you want to trust someone then you have to judge them by their actions. Its usually the hardest to judge your friends because you've subconciously glossed over their flaws. If you look carefully at the way someone does things (and this can be anything) and how they behave then you'll get an idea of what he/she's capable off. You have to be careful so you dont mis-judge people but you do have to do it. So dont be afraid of judging people. And always judge before you form a relationship with them.
