hi blades,
i dont think its wrong that you stole her. it was wrong that she cheated on your cusin. personally i think you should tell mandy that untill the breakup is final that you guys shouldent sneak around. its wrong. and if she really wants to be with you then she just needs to tell your cusin. i also believe every one has there true soal mate. and mabey mandy is right for you not your cusin. and you should let him no that.
