How Do You Stop

How do you stop yourself from falling for the person that pulled you into them and told you everything was going to be okay? How do you push away the butterflies when you think about how close you were to them, close enough to feel their moist breath on your shaking lips? How do convince not only yourself but him that the kiss meant nothing to you? How do you forget the way his heart banged against your ear? Just how do you realize when you've crossed the line of being more than just friends with benefits?
