scary emotions

yeah, i go crazy when i'm in love and this song's a great reminder, or should i say a warning, that i shouldn't let my heart go oh so easily. it's been bruised and trampled on in the past. those past relationships, pseudo or real, really hurt me so badly that i told myself that i won't ever ever let my heart get that hurt again and i never really fell head over heels in love since i made that pact with myself. i really got scared i think that i became careful, too careful perhaps that i never really fell in love since schatz. have i become hard-hearted in the process?
