You have a right to be open about this and to tell people. Of course, be discrete, but I would not allow your W to dictate to whom you can talk.
Oh, no worry there Thinker. Despite even my pre-DB shock and my life is over phase, I never allowed her to set the limits of who I spoke to. I was discrete and careful only to talk to those whom I could trust to keep it to themselves (not SP's "Themselves").
@Coach and @Thinker, I think I understand the emotion talk now. I will open up to her more. And I expect her to be the "wall" initially. Especially while I am pushing her comfort level a bit.
