how do i break up with a psycho g/f????

hah thats not pycho! Try having an gf/ex that repeatedly tried to get you arrested and/or fired. That went to your friends and told them out right lies trying to make it look like you beat her. Leaving voicemails, texts, notes, emails, IMs, comign into my work etc etc etc to try and have me come back to her…all of this after she broke up with me…

My advise to you is do this as soon as possible, and to be as blunt as possible. Break all contact.
