Eh...sounds like my friend's ex-gf.....
told her everything in reasonable way but she keep on doing unreasonable thing
So i guess ts no use in using a reasonable way to tell her things

Hmm, maybe u can try my friend's way
just ignore her when she try to disturb u by phone and msn
sometime telling something to girls to useless
they will think other way round

more sounds like my friend's ex-gf....
I agree with just ignored her, blocked in her msn, ignore her sms-es,
she will stop it eventually
