Do you know a good song about being crazy about someone (and I mean REALLY crazy about him/her) and finally the love is returned from the other person?

The guy is so crazy abou her he kills her, at first she gets pissed and kills him (in zombie state) but in the end they forgive each other marry and go on a killing rampage, so here you go love returned. :D

no Usually its just songs about people who are crazy over someone who has a gf or bf or there obsessed with them

kinda about being crazy about someone
