text: it's simple:  corner the guy and proceed to give fellatio.  (A girl like you might need to look that one up, sweetie).  Make sure someone sees you either going into the act (seeing both of you going into the bathroom at a party, for example) or sees the actual act (leave the bathroom door cracked and/or unlocked).  Or just use your camera phone. Click!\n\nWord will get back to the hated one and their relationship will end.  The guy, however, will not fall in love with you.  His interest in you will be limited to wanting to get blown from time to time.
