I think if I don't handle it well it will get ugly. I may just tell her I need a couple of more months to "let go," she may understand that.
I just feel like I have a better chance of reconciling if I am still married even if things are a bit ugly. I have been doing everything right as far as 180's and detaching. I do feel like if I postpone things she may get her head out of the fog and start to notice at some point.
I tend to agree with our Aussie friend that dragging things out is not going to buy you any points with W. But if you think that you can address it to your W in a way that doesn't make her angry, then I don't see any harm. You might present it to your W in such a way that she feels like part of the decision rather than you "forcing" it on her though. IE, discuss it with her and ask her how she feels about postponing it, tell her you could use the time to help you detach and accept things but that you want to know what she thinks/ feels about it.
