I think piecing is a slippery slope, you have to be very careful.
I agree with what you said about being sure the WAS is "really" back...
My H came home but it wasn't like I thought it would be. I should have been pushing more for what I wanted but somehow in the transition back to living together, the tables have turned/the balance has shifted. It seems I am somehow the one working to keep him home instead of him working to get me to WANT him there? Hope that made sense...
Anyway not trying to hijack. Just saying I know how it can be. In the first rush of reuniting, some of those details that should get ironed out, don't. Now I am sure you are feeling like crud because you guys were back together and now you are changing Ds world, again....I know I dread that possibility.
Keep the faith, know how much you love your D and that you are a great Dad, and did what you could to be a great Husband, too. If that isn't enough for W, what else can you do?
