You have to flavor it a little bit with your own knowledge of your W, but ONLY if you're certain you know exactly who she is.
Several months ago, I went dark for only 3-5 days at a time, and it drove my W right back in to my arms. I don't know why, but for that time period, she needed to know she was going to lose me.
Right now, I've been dark for almost three weeks, and I've not heard a word from her in her second A. I know it'll fall apart in a few months, but I've decided to move on, and file D on my own.
Follow the 37 rules, but use them with common sense. There is no one-size-fits-all solution.
