How to tell co-workers your separated - advice?

[betteroffvsmost]

I have only told two co-workers about my separation.
Just have no desire to tell anyone else.
I'm sure those two have kind of let everyone else anyway.
I don't mind that, because they don't put their noses in.
Ironic thing is, one of my co-workers is in a similar position.
How do I know that?
One of the two I confided in told me.
So I'm absolutely sure they know about me.

Maybe I am holding on to false hope that things will change more quickly than they actually will, but I haven't told my side of the family yet (two months separated).
Embarrassment? Shame? Probably both.
Unfortunately W knows this.
I'm sure she wouldn't tell them out of spite, but the day is getting closer that I do have to say something....at least to one of my brothers.
That could be a good thing, because I can show W that I'm ready to accept things and move on....or at least appear that way.
