What we do has to be for us. You can either choose to try something else to change your W's mind (which we all know we cannot do; their minds, their control).
My W's "norm" is silent treatment. So what I've been through for the past year has been exactly that. She distanced herself and detached from me and started her own life a year ago. And said NOTHING to me except when I would do the begging, pleading, etc...
So I thought I would do a "180" and push her to talk with me regarding emotions she had for me. While they were not negative, I got very little, she still would not touch on the main items of what she felt about me, and that was that. No change obvious, although I did not keep it up very long, so maybe I "gave up" too soon.
Anyhow, the point is, if she is going down the path of D, the only option you have is to work on you.
