My Friend

I met one of my friend few days back. We had close relationship in the past. At that time he told me lot about him, even the things happened before we became as friends. He keep on telling this things couple of occasions. I can't even think why he was really enthusiastic on telling those stories. I ask him "are you trust me so much telling me these stories". Some were about his girlfriends he had. But personally I believe that those shouldn't tell to others, but extract the thing that should get in to the life. It is not good for his character and people can used it as a boomerang.
But recently he has told those stories with one of my other friend with few more fresh stories. I got to know those things from others. But I didn't imply him that I got to know those stories. Because I hope he in not trusted me may be due to my problem.
But when I met few days back he was thinking that I was hiding my stories from him. I was really upset because I know he was the person hiding the truth. But I didn't scold him, said him
"If you are hiding some thing from me that means you doesn't trust me, isn't it?"
He got nervous and shied.
In the late evening he send me a sms saying that "please be my best friend for ever, don't change in the future"
