From the movie 'Fifty Shades Darker' a song by The Dream which is 'Code Blue' has these repeated lines.

That's what I get for loving you, code blue
That's what I get for loving you, code blue

As far as I've learned Code Blue is-

Code Blue (emergency code), a hospital code used to indicate a patient requiring immediate resuscitation.

1. Why does he get code blue? Is the separation making him feel like he's dead?
   
2. But then, when she was with him was loving her also code blue then? As he only says that's what he got from loving her.
   
   
3. Why does he feel like crying when he is close to her?

The closer I get to you; The more I feel like crying.

I'd appreciate any help as googling didn't help much. I'd like to get somebody's point of view or maybe a succinct clarification.
