Mmmmm--just remember that the final part of Stage 6, Acceptance, is a settling-in period of 18 months or so!
It also coincides with Piecing, the stage where the LBS gets her spouse back, and suddenly discovers that she's being tested on every change she made, that everything she pushed aside to focus on the goal of "winning him back" is flooding unbidden into her mind.... Some days, the relationship seems great, better than ever, and other days he goes alien again, or everything he says is a reminder of the most painful time in your life and somehow you've lost all the certainty you had when you were an LBS and you're wondering if you're going to end up in a depression....
The sad thing is, your ex's journey could be speeded up (and perhaps his depression could even be permanently alleviated) if he got good counselling. Can none of his concerned friends persuade him to get it?
