"What you are doing is so disgusting."
"What are you doing is so disgusting."
If it is not meant to be a question, I think that the first sentence is correct and the second is not. Am I wrong? I know that this is very basic, but I am confused what I have recently heard from my native english speaking roommate. He sometimes use the second sentence I have written above.
Thanks in advance for your reply.
The first one is correct.the second one,with the given punctuation,isn't.
