Detachement... When you detach completely, you are "gone"... I struggled so much to decide whether I was really detached or not. For some time I had put my H's thoughts on pause. And it worked as far as pain was concerned and functioning and actually enjoying life. When I allowed myself to fall in love with someone else, I decided I wanted to, I took that step beyond. I was gone. And he felt he was running out of time.
There is a fine healthy line. And it is hard to keep walking ON it for long.
