@saltandpepper sorry for taking so long to respond. I've just had no energy and been sleeping a lot. I've needed it. Thank you for sharing your story.
I'm glad that you eventually let go of this very toxic friendship. Sometimes we hold on longer than we ever should have. I was in this position at the beginning of this year. Not the same as your friend, but it had been a very long term friendship. About 24 years. Know each other since high school and had been through a lot together.
I realised that this was someone I wanted to and NEEDED to say goodbye to forever. Do I regret my decision, not once. He had never cared, seen nor understood the value of friendship. He had abandoned me and the friendship more times than I could count. There one day, gone the next. Lost touch a few times, reunited a few times. In touch and seeing each other for many years, then gone again.
I realised he resembled facets of my mother. He was not my mother but had facets of hers. Dropping me like a hot potato when a man came along that was to become his potential new boyfriend. Telling people not to tell me of their time together do I wouldn't tag along. Just not being a mature adult and saying, just want some time with my boyfriend, but can we hang out another time? This emotional games went on for do many years. I did not realise he did not value our friendship at all. Till the beginning of this year. I decided after looking at 24 years of history, my beliefs about our friendship and so on, that I'd been lying to myself for a long time. It was a toxic friendship that I was genuine about and very loyal to and absolutely adored him. We shared so much history.
However, I knew in my heart that I was ready to let go for good and never ever go back. I do not regret my decision to walk away and say goodbye. I do not miss him, I do not think of the good times, I do not think about what could have been. It was basically long overdue.
I did send him a goodbye letter. I don't know if he would have ever read it and I don't care. The letter was for me, not him. I'm glad it said goodbye. I always gave more to that friendship than he did and I also realised that he needed professional help.
Through this year, I've done a lot of painful growing and changing. The origin of great damage to myself, my mother. My father too, but they both individually caused me a lot of psychological damage. I cut contact with my mother at the end of last year, and my father 11 years ago. He is still living, but to me he actually does not exist. To me he is already dead. I buried him already in my own way. I have put down a strong boundary that I'm not to be contacted at all by anyone, if he is sick, dying or has died. I have said it will go ignored if anyone contacts me in regards to that and I have stated it is a boundary not to be crossed. I have said firmly, he us already dead to me. I got no response, but I made it clear where things stood.
I meant it and will act on it. My mind has not changed, nor will it ever. I'm simply not interested.
As for my current situation, I can't talk about it much yet but I lost respect for this person. I need to deal with my own situation one day at a time and do things that are right for me when they are right for me. I have laid strong boundaries down and mentioned the consequences of my boundaries being overstepped. It's progress.
