I do not believe in a single word that your girlfriend is telling you.Man you have a CRAZY girlfriend to say the least. Your relationship has RED FLAGS for everyone. YOU should seek some help for yourself (psychotherapy) in ordee for you to develop skills of sef respect and self esteem.
I am an attorney since 1989 and an advocate for victims of domestic violence,and let me tell you something,everything you described here I saw before, do not walk but RUN, your gf is not a victim here,she is VERY manipulative,and the divorce story is a complete bs.
