Yes, my W did make a decision to become involved with another person. But at the time, her mother had just died, she was depressed, and was turning more and more to alcohol. The other person took advantage of this, whether he knew it or not. Therefore, he is slime.
Do I abdicate responsibility from my W? Of course not. She should have come to me and hit me upside the head with a brick to get my attention if she needed to, but she chose not to. And I am not saying I am without fault, I certainly did my share to screw things up as well, but overall, we did have a very good marriage. It is only now through W's re-definition that she is trying to convince herself otherwise.
By the way, I call the other person every name in the book when I am by myself, but I do also pray for him and his children.
NYS, isn't it amazing how our Ws can fall in love with these "Psychopaths"?
As always, thanks for your responses and keep them coming.
