I "recently" went Dark with my WAW but more as a result of me giving up on our marriage...

I went dark barely talked with her was very short and curt when exchanging kids and planing schedules

For the first while my "Ex" was fine with it but then I stopped and talked breifly about something else and after almost 2 months of Darkness... something "broke"

However it did have the negative reaction of leading her to start a relationship with a new man (I'm hurting over that one)

I think I missed the boat there... by beeing a little to cold and distant while she was telling me how she was feeling and her reaction opened up the old wounds and feelings in me I had closed of and was healing...

But it has brought us much closer together then we were before...

So in my case it worked and it opened a dialog between us that "might" and I mean that in the most miniscule way "might" lead back to something between us.

So if my example means anything...

It could be worth a try.
