I guess where I get confused within my own thoughts is how this applies when I think about “doing what works”. In one sense this does work: it draws him closer and builds a connection between us. He initiates conversations with me, I never initiate with him.
I am cordial and upbeat (and genuinely feel that way much more often these days). I am inching closer and closer to true acceptance that he is gone.
I just don’t know how I can pull back any more than I have? So am I “doing what works”? In one sense, yes. But clearly he’s seeing what he would be missing if we D, and he just doesn’t miss it. So in that sense, no.

There’s obviously the possibility that he’s so far gone that nothing would work, but given the purpose of this forum that isn’t worth spending energy on, because that would be giving up.
