master of my mind, slave to my heart

Have you ever...felt some way about someone but were to....not scared, but unsure about what the outcome would be if you reveiled this....this feeling u have. Like, you're not unsure because you're a pansy, infact you're the direct oposite, but because you are afraid of the uncertain. Afraid of ruining a good thing. Not that your scared of rejection, but rejection from this person. My mind is sayin don't do it but my heart grows heavy. I'm the master of my mind.......but a slave to my heart. So the question remains, do I listen to whom I am ruler.....or to the one who rules me?
