dear wang hai,
i am sorry to hear that your friend had hurt you .you said that you put your trust in him,shared your secret with each other,but he failed to keep it.you were worried about this.now,i have some suggestions for you on it.if he just did it once, please forgive him.maybe he had done it by chance.but if he always did so and never apologized for this.you shouldn't regard him as a friend.you trusted him so much but he hurt you so much , he never cared what you thought.You must always take what he says with a grain of salt,tell him to get away from you from now on!friendship is very important to everyone.but fault friendship isn;t worth cherishing.toleranc,sincere and understanding are the most important things in a friendship.
your sincerely,
