I can speak from pre-DB experience in saying that pursuing for the talk does not work at all. If you were pursuing before, a 180 on that would be not to pursue. That's what I did. It took 8 weeks to show any effect.
W is talking now. Very limited, very sporadic. She still wants out. I have told her I'm not stopping her.
That's the only option I have left. I tried everything else.
