True. The cycle of devaluing trust is a forever long cycle, which I'm unable to comprehend if it is the choice of people or the consequences of being too naive.

However so, we will keep on trusting whom we want to and we will continue to fall in the pit until one day when 'trust' will not remain just as a word but it will attain its true value.

Until then all we learn is to gain control in being less violent to self by not letting it all affect one, but that doesn't mean we become ruthless. So, yeah, a lot of learning is there when trust is broken. And, I believe the longer we live the more variant kind of trust issues and none trust issues we will face. It is a cycle of life, it winds and unwinds.
