To know or not to know?

I want to know or i don't want to know?I cannot decide.Today he told what happened and what he did that day.Then i get to know that where he actually went,what he had did for the day.Do i want to know all that,i felt relief to know that.But when that particular moment he started telling story,i suddenly felt that i don't know what respeonse should i give.Should i just listen to him?Should i give comment?I don't know.I think i act weird.He felt so too.May be at the same time he started to worry that am i going to tell anybody else,of course i won't,if u told me no to do so,i promise i won't.
Anyway thank u for telling,and this cleared up a lot of things.Thank u.
