nsw, you and you alone are responsible for this mess. You are a selfish, immature jerk. You have been given excellent advice and you actively choose to piss it away. You decide to do the worst possible thing every single time and hide behind excuse of "oops, I did it again." I think your ex made the right decision to leave and I hope she moves forward with her life without you.
If you love somebody, set them free. http://tinyurl.com/2empx2g
