Don't dissuade anything. Your wife is an adult who is responsible for her actions. She poached another woman's husband. Let her answer for that, not you. I admire the OM's W. She's not being passive about this at all. That's a good thing.
I decided to not to dissuade, my wife deserves to be confronted by OM's W.
I'm still hurting all the time, but I think progressing in detaching. I hurt for myself when I imagine my wife gone from me, but my biggest pains come when I think about my son, and what a D would possibly do to him, and even what this Separation may do to him; he's truly the one getting the shaft with all this.
Thanks.
