Interesting.
The I inhale, inhale, inhale and then the little exhale is very clever. To me it seems as if you take take take and get little back with love (or lust).
The second stanza is my favourite. "I exhale and my soul is full of light," it can be interpretted as 'there is light now it's over,' but there's also like giving abit of hope for the relationship.
Very nice. Not too long but not to short. Straight to the point.
