Just based on what you have written above, I would say to pull back a little bit. It seems that he might be overwhelmed, as you have mentioned he is acting distant and a little moody. Probably the more you push him, and the subject, the more he pulls away. My H is doing the same right now. For now, it seems, he might need a break from relationship talk and that sort of thing. Does it seem like he might need a little bit of space?

I would try giving him a bit more space and gradually work back to doing more with him, gauging how he responds to what you are doing. "Lovingly distance" as they all say...Have you read Divorce Remedy yet? I found it to be very helpful.
