What's the difference between ~지 않다 and ~질 않다?
Is there a big difference between these two? I hear the latter much less frequently than the first and I'm guessing there's just a slight difference in nuance. Here's an example I heard in a song:

"넌 나와 같을까? 뒤내어보지만 감이 오질 않아"

Is this simply a future tense form of not? Like the feeling is not going to come back? Any help is appreciated!

Answer

I believe "~지 않다" and "~질 않다" are the same.
I also believe that they both are present tense.

#1. 집에서 나오지 않아. 
#2. 집에서 나오지를 않아. according to a Korean dictionary "를" is emphasizing word here.
#3. 집에서 나오질 않아. This is way you speak #2

So "감이 오질 않아" is you are emphasizing you really don't know if he/she has the same feeling that you have for her/him.

Please note that "나와 같을까?" can be translated many different ways depending on situations/circumstances.
