Hey Cyprian,-- Great question & thread topic. (Check out my story in the ex-bf/gf relationships Forum: still crushed 12 years later.....)
Boy oh boy is this a huge thing in a breakup. I have replayed my last conversation with the ex millions and millions of times in my mind. I was so destroyed after the relationship disintegrated... I needed to see her one last time before I moved away (with my new gf (and future/present wife)). So I set up a meeting at a bar/restaurant we used to go to.
Uncharacteristicly of me, I really tore into my ex that day. (I always treated her like Gold)... I purposely met her in a public place so as not to have the situation Blow-Up. My words were carefully chosen and delivered to truly express my disappointment and spite.
It was like a true role reversal for us. I definitely planned mine out ahead of time. I had a clear and present message for her. My pain turned to Anger that day. I was "Fired-Up" and vengeful, while she was emotional & confused. I started NC right after that moment, literally disappearing into thin-air the next day. Out of her life, forever and completely! 12 years later, I remember that day so vividly... I think about it in the middle of the night all the time, still.... very haunting.
I'm glad I had the opportunity to do this. I never could have moved on without that last conversation. I was happy with the way I expressed myself, it felt good to get-in-her-face alittle. She needed to be put in her place finally, she had treated me pretty badly toward the end... but I always loved her so much and I wanted it to work so badly that I never really cut into her like that. It was hard to do, but something I had to do!
I say plan ahead, and really get to the heart of the matter. Tell'em the truth! Good Luck !
