Thanks for the encouragement. The part you mentioned about the loyalty to the OM is what's killing me as well. Its as if giving accepting the marriage is somehow a betrayal to him. And the saddest part is that he is married in another with 3 children. With no intent on leaving his family. But my W was willing to simply be the OW. Even though she now claims that their just friends with no intent on going any further. Which I believe is another lie.
I discovered yesterday last night that my W is also in contact with someone else via Facebook that she cheated on me with. Apparently she claims that only a kiss happened between them and from the messages I found between them, I believe that no sex took place. But that doesn't mean that more than just a kiss took place. I have decided not to push on what more happened between them. But a few weeks ago, she removed him as a friend on Facebook, but I noticed that he liked a photo of my W and S13 when they were at the park yesterday. I checked out his page and she had liked a new profile picture of his. And when we were lying in bed, I noticed that she was following him on her timeline. But still aren't friends on Facebook. So somehow they're able to be on each others timeline without being friends on Facebook. Not sure how they do it, but it adds a whole new dynamic to sneaking around. And just when I figured that there might be some small sense of loyalty returning on her part. Do you and your W have any intimacy going on at the moment(holding hands, kissing, etc.)?
