Most Helpful Girl
Some people just don't have any empathy. This guy not caring about what you think and your ex sticking around your life. I am sure this guy is really a "winner." Also, I think she is probably doing all of this for attention and for a reaction, not saying that she is not into this other guy though. You have given her exactly what she is looking for though, attention. You can either stick around and ignore her. This would mean being tormented, but also having social support around you, or you can move and won't have to deal with her. Maybe find someone that doesn't require that sort of attention. If you have a little bit of money and time, you might try going to a life coach that can give you tips on how to deal with this problem and move on to something new, and healthy.
