I think some have missed some things that I posted so I wanted to clarify:
I did not EVER want 'revenge' on the wife, I feel sorry for her and I admit that my thoughts did not turn to her until I knew how she felt. Selfish, yes, but I am trying to be honest, not just say what people want to hear.
I had a choice, my choice was to either walk away, knowing that he was now in another affair, his situation hadnt changed, only his cake had. I would then feel the guilt of knowing his wife was being cheated on, plus the pain of knowing he had replaced me.
My other choice was to tell the wife, my pain is the same, the (other) OW womans pain would be probably like mine, the MMs pain would be great and the wifes even greater.
I chose the latter, not because I want to inflict pain on anyone, but I felt it was the right thing to do, even though it was driven by anger and revenge.
Also I dont think I said, maybe I did in the other thread, but I contacted the (other) OW a few days ago, she didnt know about me, I asked her to contact me and she didnt, and I can only presume that the MM told her not to.
When I told the wife (through text message, which was as polite and kind as I could manage, and also said I regretted the affair and was very sorry) I tried to make sure that it was a good time for her and that the children wouldnt be there, I had no way of KNOWING that, but I thought about it.
Thanks again for the supportinve posts.
