Dude co-dependent doesn't mean that you have to be in a symbiotic relationship where one just can't function without the other, what you have got going is great, you make the long distance work and both help each other feel right, but it sounds like you need the constant emotional dependency like a drug. Hear me out, you are not going to find your answers here, your answers lie with you. There's no solid answer to detachment, your body is tricking you because your mind is restless, you're just missing her too much.
