Two months ago my ex broke up with me and told me he never wanted me in his life again. So I said fine and walked away from his life , he's layed hands on me before cheated on me , including knowing things he thinks I don't know of. Recently I got in touch with a friend that works with him and told me he was throwing dirt on my name and said he had been fucking girls while we were living together. I got so mad , so I went and told my best friend and she came up with the idea to slash his tires and scrape his car up. She ended up doing it last night and she's like while I was doing it I thought of all the times he hit YOU and left you in pain , , was it okay that she did this was it only right? Or should I have stopped her?
