Hi
i´m sorry for my bad english but i try to explain myself in a way that you´re able to understand
We dated for 3-4 months
She went study abroad and cheated on me
I thought i go crazy after all the gaslighting but in the end her monkeybranching didnt work out and right now she is dating some other guy who is looking like me

After i learned about narcissism and bpd i now know what happend
Our breake up was bad i called her names after i found out what realy happens and she blocked me everywhere
then one month ago i told her that i cooled down and i dont give a
PLEASE READ what happens but because her brother lives right next to me and everytime i see him and his family i think about the way we ended the things and i just want to be cool with everything so we dont get into awkard situations when we see each other ( i saw her for the first time after the breakup 1 month ago and it was awful and it was ofc next to my house while she was visiting her brother but she didnt saw me)
She didnt respond but didnt blocked me
And i saw her few days later again near my house while she was visiting her brother and this time she saw me
i went outside and was wating for a friend and she saw me and damn that was funny as hell because at the moment she realized that i was there her head looked like a tomato and she tryed to hide behind the bushes so i cant see her.
Then i went to my car to grab my jacket and in the meantime she went home and we saw each other but she didnt looked at me instead she looked straight on the ground like she trys to avoid any contact.
for me after i saw her like this for the first time my heart beat went crazy
The second time i drive by with my car and she saw me coming and again her eyes went straight on the ground.
This women is done for me because after all the lies she told me... i mean she lied about everything her past, her partners she had, her "character" and after the cheating im done anyway but somehow i think about her everyday now because her brother live right next to me.
We broken up for 5 months now and i had some one night stands but im for sure not ready for a relationship.
I´m on a good way but because of her brother it bothers me a little bit that we are still "enemys"
I´m sure she has some sort of disorder because after i learned about narcissism and bpd everything fits.
Idealization, devalueation, discard, the mirroring, gaslighting, future faking, all her exbf are crazy cheating bastards...
So what do you think should i speak to her when i see her next time around my house or should i stay nc
I dont want anything to do with her i just want to clear things out, talk about normal things not the break up so when we face each other its cool between us and not awkard
Like when i see her i can say hello and move on and dont have to worry about what is going to happen now and get crazy fast heartbeat.
