Sorry if I'm out of topic but, I can't help my self cause I disagree about this, about reconciliation is less possible with a vanisher. I don't believe that, it's not my experience.
My thoughts , with out real academic knowledge in psychology, is the same as what they say about narcissists. They are really weak inside, terrified of abandonment real or imaginary, terrified of stronger or more stubborn people, yet can't remove themselves out of the "victim zone" and show remorse. I think reconnection is totally up to the LBS with vanisher. They will connect, might take years, but every thing is about how the LBS behaves.
I know 3 vanisher;
My dad, vanished after my mums affair (1980) for 4-5 years, tried every way there is to reconnect with me. He had some real abandon issues. Was up to OW#25 or something when he died. Ended up in jail for shooting one woman who wanted to leave him. Played the victim card all his life.
My mum, I've been NC for 6-8 years, got a Birthday card when I turned 50, really strange card. Silly me broke NC and called, no answer but she called back 30 minutes later. I did not take that call, I decided I can't take her narc behavior.
A couple I know, they split up cause the W vanished and ran away with an OM, remarried and divorced within 5 years. During the last 15 years she tries everything to reconnect with the LBS but he is remarried to another lady.
They all reach out over and over again but the "left behind" does not want the reconnection and/or reconciliation (moved on) OR does not have that agape love. I don't even know if I have agape love in me, can you have this kind of love towards people who abused you or done things to your children?
Sorry for bringing up another topic
