I think it is too soon to start expecting changes. As of now, he has to figure himself out.
If you notice a lot of sitches here have gone on for months and months. 8 weeks seems too soon for both of you to change or for any changes to stick.
I would say take it slow. Don't make any sudden decisions.
What will you do when he comes home? be casual, talk, but try to avoid too much R talk. As he says, see where it goes. Concentrate on yourself, your changes. Be the good example.
Don't try to push your H into something he is not ready to be yet. Remember, you can only control yourself, and not him.
Ask yourself, what do you really want?
Your H at least seems to be willing to work on it. Perhaps he has to learn, one thing at a time, what it takes to save the M.
I have been in my sitch for almost 2 years now, we started piecing last November. I can tell you that a long time ago I started seing what I needed to change, and understanding why things happened as they did, but untl now, I make mistakes and backslide. I still have no expectations of my H,because when I do I just get disappointed. BUt I see him coming along as well, and appreciating the time and space I give him to figure out things for himself.
I think you still both have a lot to learn. It will be a rolleer coaster, so fasten yur seatbelt. I think you still are not in piecing, to be honest.
But it does seem like you have a good chance....play it right!
