I was dating a girl for couple of months, everything was great, awesome chemistry and amazing sex. I lost frame, didn't maintain abundance mentality, was too available etc. Basically oneitis. She ends up fucking her ex. I soft next her and keep her around as a plate for another month. She ends things with me saying she doesn't think she can do this. I don't really argue with her but I tell her she a bitch and I'm better than this.

Went NC for the last 5 weeks and started looking for new girls. Went on some dates, closed with 2. My ex and I work together but in different areas. The last week she has been coming around and talking to me, smiling friendly etc. I have remained stoic and polite. Previously if she saw me she would look away, avoid me at all costs etc. I have no intention of dating this girl, but I'm curious as to what is causing this behavior. Thoughts?
