My girlfriend is threatening to commit suicide if i leave her, help?

Hey im sorry to hear that , damn man your getting taken for one hell of a ride, first off i would make it clear to her parents, my parents, and all our friends what she has been saying so later on if by any chance something goes down its not your fault, Then right after that id annonomouly call a help hotline and let them know her name address and the situation. Then just end it, you said 2 months, thats nothing. She need help and if you really think something might go down as in attempted suicide or actual suicide make sure you make it clear to everyone you talk to and that knows you that your gona break up with her and shes been saying this crap.
