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

leave her with me for a night. shell never talk to guys again. in all seriousness though i had a wacko stalker crazy bitch g/f and i couldnt dump her she like wouldnt let me id say its over and shed be like no its not. i finally figured ouyt you cant do it when your mad at each other. one day i just came home from school and we were talking on the phone no issues or problems or anything and i was like Ok well i gtg now becuase i dont feel like talking to you because im tired of you and its over and blah blah blah. hung up and thats what finally did it. i mean yes she called for a while and showed up at my door and classes and was always talking to my friends about me but she eventually went her own way after about 2 years of that… in retrospect i guess it didnt really work that well. i dunno… donkey punch her if all else fails.
