IDK: WAT THE h**l DOES HE MEAN BY THAT BESIDES IDK?

and then a moment ago i try to break the ice by saying: you dont sleep much do u?

and he doesnt even answer me befere he signed off. ARG!

SOMEone decipher this situation for me.

Answer 1

IDK may mean I don't know...I think it will be better if you create your own account so that there will also be some sense of privacy. Besides you don't know yet if he likes you and if in case he likes you he might  not feel comfortable thinking what if it is your sister and not you talking to him or what if someone else read his message for you. If you really want to talk to him, better do some research like what is the topic he can't resist talking about, speak his linggo so that the icing will break...

Answer 2

He probably thinks your a little weird. And he said IDK to not try to hurt your feelings.  

Answer 3

I'm having a harder time deciphering your question.
