[Basically I was thinking of a slow divorce. Just civilly start separating our stuff. And live like we have been until we do dicide to divorce. but I will no longer be committed
What do you mean about no longer being committed, and acting divorced until you "decide to divorce"? Are you just looking for an excuse to date others without actually having to be divorced? Are you daring her to date others? Are you trying to threaten and manipulate her to change so she'll start acting the way you want her to so you don't go through the divorce?
I just don't understand what you are trying to do...
The whole situation sounds really uncomfortable, wishy washy and unhealthy to me.
There is no arriving, ever. It is all a continual becoming.
