Ok so it's been 3/4 weeks that I broke up with my ex (first girlfriend) when I knew she cheated on me 2/3 times. She was litteraly crazy, she even went to a psy hospital for a while after trying to commit suicide. When I broke up with her, she was begging me (for approximatively 1 week) to forgive her and that she promised that she changed and don't want to do it again. The thing is I ghosted her a day after I broke up with her. Time to time she tries to contact me to get "some news" and ask "how I am feeling". No answer.

The thing is, how to act around her if I saw her, like in the train ?

I thought about two ways :

  1. Ignore her
  2. Act like it's no big deal and that I grew up from it (been hitting the gym since one month instead of getting mad at her for nothing), and act with the abundance behaviour.

I would prefer the second option because it shows that I don't give a damn about her anymore and that I am getting better at everything I am doing (I am a student working in a IT company at the same time and basically, I am a lot more rigorous than her, have a lot more money than her, better relationships (she always stay with losers)). I ultimately want her to beg for me to come back and have the power to say "sorry but no".

​

What ya'll think about it ? What should be the best way to behave ?

Thanks.
