He didn't even call her to end it. She went looking for him and even tracked him down at the gym where he works out at to find out why he hadn't been calling or seeing her. I called her and let her know that I knew about it and that she better stay away. My H and I are recovering wonderfully and haven't heard from this OW for 6 months now. The W in my situation never did confront me, and I think that it would have helped put closure to this for both of us.
Confrontation is a good thing, done in the right way.
But I think that manipulation is a totally different matter that usually ends up backfiring, and in my opinion, that is the way I think the above situation was handled. That is only my opinion. He's a worm. He wants it both ways. I say that he stayed with her out of fear, because she manipulated him, too.
