Will other people blame them though? Maybe that's some consolation. If I do manage to CTB, I find it somewhat consoling that my oldest friend knows where this all started. It's not exactly all due to this other person now but, they certainly set me on the path.
I don't think they'll ever feel bad about that. I believe them to be a narcissist. They used to and likely still do twist things so that they're the victim. I suppose to some extent, they were- neither of us wanted to be together growing up. Still- these sorts of people do care what others think of them. So, I suppose that's the only thing to feel consolled by. That some people will know the truth and judge them badly for it.
