Many times if we love and like someone we can't see their bad parts and their bad behaviors, that is why we get hurt many times, so we need to start seeing what they show us instead of all good things about them.
Trusting will get you hurt, no one will care for you, all peoples are taking advantage over those kind of peoples.When I was young I was very gullible and trusted everyone. Many powerful people have ruthlessly exploited, cheated and robbed me, so I do not trust people easily now, I am more careful .
