I dealt with a similar issue. My 'typical' behavior with my W would have been ignoring her basically. So when I went dark, I feared that she would see it as me just being the same as always. It worked out just fine for me.
But I do agree Country, your sitch IS different than mine bc your W is not in the angry stage that is so common. Yet she IS having an active A. So I see your dilemma. I'm a little torn on what you should do.
You know what I would do? I am just thinking out loud here. I think that I would jump to the middle of my sitch where my W was being somewhat friendlier with me.
What I did during that period was let her initiate ALL contact. Be polite during all contact. Keep the conversations short and to the subject. Finally, make sure that you are the one that ends the conversation (bc you are busy doing fun stuff preferably).
What do others out there think of Country's dilemma?
