I'm confused, my understanding was that you were pushing the sep and the D because you don't want to be married to her anymore.
But in any case, what is the point of telling your Ds tomorrow? Are you officially separated yet? If not, I'm not sure how it helps to pull them into the drama other than reducing your stress. But there are other ways to get support...
Can you just let things be for awhile while you and W work out the separation? It seems like everyday you are trying to do something new to get a reaction from someone, W or someone close to her. These manipulations aren't going to cause W to get it and decide to warm your bed.
Finally, I guess you were making a wry joke, but I think it is a poor choice to tell Ds on Inauguration Day this year, especially if they were at all excited about the election. This could very likely be the most important inauguration day of their lifetime. For many, it will be a very moving and joyful day. Why risk infringing on that?
