Wow, kudos for tackling such a difficult topic in a skilful way. Some very good points here! It sounds like you've really grown through your experience. Proud of you!

However, I do think this is a case-by-case basis. I've only ever cut out one person in my life, and it was after almost a year of contemplating whether to do so. I had tried again and again to save the relationship but it just wouldn't work.

And it's not like I was 100% the good guy. I definitely did some shitty things. But I also tried my best, and in the end, I believe cutting off contact was better for the both of us.

I do acknowledge that I probably hurt this person. If you're out there, I genuinely wish the best for you. I just don't think our relationship would have worked out.
