H, Do they know that they are reconnecting? Deep down I believe they do on some level, but not on the conscious level. You have to remember, they don't always remember all of what they say and do during the crisis.
If the ow is still in the picture, it's not a true reconnection process. During replay and throughout the crisis, they can have touch and gos and we can misinterpret them as complete reconnections and they are not. As long as the op is in the picture, it's touching base w/home, i.e., holding on to that one loose thread of sanity w/the old life.
Schedule a time that is convenient for you to have your h come over and pick up a few things. I would be at home, but busy when he comes over. If he wants to chat, treat him just as you would a friend. Don't ask questions that would appear to be of a personal nature to him, don't bring up the relationship, etc. Follow his lead in the convesation department.
