Kim, do you think that his run in with his boss would be a wake up call to him? I think you handled it well when he asked about his change in behaviour.
I too admit that I have problems understanding the friends after divorce thing. Sometimes it is so natural and I think yes, I could do it. Othertimes, I think it is so hard, and it would be easier just to leave town. That's me ~ 4 seasons in 1 day!
I do hope yourtalk with H and his talk with his boss have made him question a few things in his life. But I wouldn't hold my breath. Just keep living your life for you, and leave that door ajar just a little bit for now
