I didnt't know ...

[relativist]

I wonder what is the correct form:
"I didnt't know that you will come."
or
"I didn't know that you come."
I mean that I didn't expect him but now he is.
Thanks for help.

Welcome to the forums, relativist.
You could say:
"I didn't know if you would come."
"I didn't know that you were coming".
