Building a trust on others takes a lot of time but breaking up someone's trust does not even take a minute. Why do it happens that when we start trusting someone at one point of time, that person breaks it up at another point of time? When we share our feelings with others, trusting them that they won't reveal it to anyone, then why do they make it a source of their gossip with others?
I myself have experienced this a lot of time. When I was assured by the person that my inner feelings will not be known to others, then what makes them to tell others after making several promises of not revealing it to others. For me, my feelings are very much important but for others it is just a topic of gossip. So please do not ever break anyone's trust because it really hurts other's emotions and after that no one will dare to trust you again.
Respect others feelings and emotions without letting them down and making them feel guilty that why did they shared their feelings with you and trusted you.
