Great, honest article @florinmanica! I can tell you have been let down by many people in your past. But I don't think we have to automatically expect the worst from everyone we meet in our lives.

Such an attitude builds up a barrier that the other person is unable to cross. If you give trust on the other hand the person has the chance to return the favour.

I'm not saying you should trust everyone but usually we can make a healthy judgement about who is going to hurt us and who won't.

I have actually just recently written an article about this topic is as well. It deals with forming relationships. https://steemit.com/psychology/@restlesswanderer/life-lessons-chapter-4-lonely-wolves
