How do you know

How do you know how to breathe me in?
When youre my oxygen.
How do you know how to hold me when it�¢ï¿½ï¿½s me, and you?
How do you not tremble when youre in our bed alone?
Cause shaking is all I can do to keep me from dialing your phone.
How do your words capture me with every emotion that you possess?
Baby with out you Im a mess.
How do you have so much belief in me?
When I cant any within my self.
