.BEEN reading your previous threads : i think you are not
totally at fault , only partly .The girl doesnt know what is shame
or modesty for a lady.iF I am a guy and this girl literally throws
herself at me , i would eventually accept you.She needs to know
that if you truly love her and want to be with her eternally , you
would be able to resist temptations and possible challenges that
will surface in this relationship.She has a high sex drive
Love,sex and possessivness cant keep a man's heart.She must know
that she cant keep your heart no matter how she seduced you with
her affections ,threats and her body.She jolly well should know
that any other girl can sleep with you as a confession of their
love and devotion to you. You better handle this affair
sensibly.She is getting more possessive and revengeful.sounds like
a psycho to me.If you have grown tired of her,please sever all ties
with her ,dont let this drag on or i forsee a possible life and
death issue here.This girl needs to know that love cant be
forced.Why is she so bold sexually?i dont know.She is like a
pest,so thick-skin...her behaviour wouldnt earn the respect of any
guys.If you wanna break up with her , ask her out for a dinner and
tell her you need some time for yourself,or let her know you would
prefer an open relationship not an exclusive one.
Lastly , please dont impregnate her.If she becomes pregnant with
your child,she has winning hand and you have to marry her .Refrain
from having any intimacy with her.The girl nows wants you body,soul
and your life.Got it?
how to break up with her :
i hereby recommend 6 methods,the trial and error kind
(1) Missing in Action : This wouldnt work since this girl is
probablygoing to pester you 24/7 until you give her a definite
response
(2) Treat her badly (the sly method) : treat her like a jerk,let
her detest you and she will get over you
(3) chat to her heart to heart :probably the conversation will ends
with a sexual intercourse,since this girl doesnt really know how to
control her sexual desire for you.
(4) aSK A friend or a confidant for help :get him to explain things
to her in your presence.Its like a conference between the affected
parties while the friend acts a middle man
(5) Tells her you have become a gay suddenly and your bf is some
wrestler 
(6) ask her to log on to www.sgforums.com and read your
postings.LET HER KNOW how you are tormented
