Left,
To be honest with you, this is exactly what your h is going through 24/7 and it's not a pretty picture for him.

I'm sorry I don't know your whole story, but from what I've read here, I would have to say your h is more in the replay stage then withdrawal. The true withdrawal stage is after the ow is out of the picture including out of his mind, and he's moved on beyond replay. Replay, especially if there is still some of the anger stage can become volatile at times and they will run again. Things are not settled in their minds yet and they are still in the "teenager" stage and truly don't know what they want. They can act withdrawn in this stage, but it's more of a replay/teenager type of withdrawal. I'm not sure if I'm making sense, but if you read Snodderly's thread you mentioned a few more times, things may be a little more clear.
