My ex lives across the street and refuses to leave me alone, NC on my end has worked for me to a point; I inevitably hear and see her, I desperately want to reach indifference to her. I agree with enlighten me; for us who can't have 100% NC, I think if we can desensitize it will help to detach and heal.
I had 5 months of no face to face with my ex, when one night she walked over and surprised me; she acted like we just saw each other a few days prior, and her behaviour had only gotten worse. I felt better for a short time; seeing her after learning about BPD, showed me just how much FOG I was in. Didn't take long before I was letting her in again; mistake every time!
I don't look at her property because it hurts too much from what we both showed each other in our relationship. I try to ignore her and not give her the attention she wants, like you; I don't even want to say hi. I have tried some LC recently, but didn't go well.
Good decision on your part to do what you felt was best for you.
