Sounds like you are doing a good job of detaching and GALing Nblsost. My H and I lived in limbo land like that for a while too. Until I actually moved on in my heart and mind and starting planning my life without him, he finally woke up and realized he would lose me forever. Until then, he was playing me and the OW keeping his options open. In my opinion, he needs to feel like you have moved on and he has lost you. When that happens you will know, because he will do ANYTHING to keep you, including no contact with OW, full transparency, changing jobs, etc.
Man, if I have read this (or something very close to it) on here once, I've read it 500 times . . .
