I have to agree with Cathy. Think of him like a friend so that you don't have any expectations. I definately see this as your H is trying to come out of the tunnel. The trick is to not scare him back into the tunnel.
If things continue to progress well, don't embrace him with open arms yet. I would still be mysterious and wary.
From all the good advice I have gotten, it seems that unless your WAH really senses that he may lose you for good, a reconciliation won't last. Then again, I speak this from experience. LOL!
