Lived the same story and it took me almost two year to leave the bitch.
she cheated on me with a married man, during one year i got doubt but no evidence.
Finally she left her "married toy", the guy was so in love and gone crazy so he called me to tell allll the truth...
Guy spent hundred of euro in gift for my ex bitch, she sold all the gift on ebay to make money.
Guy suspect her to cheat on him (lol) with other guy, so in theory she cheated on her married lover, at that point i didn'it know who was the boyfriend and who was the amant .
He was so desperate that he want me to give him her facebook and msn acount to spy her...
He divorced for her, and she left him.
Worst bitch got the strange ability to hook honest men.
They know how to manipulate then easily.
so my only advice is get out and never go back, asap, before you fall in depression, before you start losing hair, before you start losing willpower for bbing, for sex, and for life in general and before you start too drink when you come home after a night at work.
i'm now with a smart beautiful girl, born and raised in a stable family.
My ex lost her parent at 4 year old and grew up in a shitty family.
she will search for a father figure all her life (thankx to getbig advice).
she's a beautiful girl, but total shit inside.
