My sitch is this. W unilaterally walked out 5 months ago. She led me to believe that a reconciliation was possible -- nice some days, mean others. I worked my tail off DBing, while she proceeded (or continued-I don't know) to have an affair right under my nose (and the noses of our children).
I confronted her. She admitted. A day later, she recanted saying she made it up to get me off her back.
Classic MLC!
Meanwhile, she was always of the belief that if a person wanted to mess around, they ought to get divorced first, not cheat on their spouse.
She is indignant, acting as if she had a right to have an affair. She even said I would take her back tomorrow if she asked to come home. I told her I would not touch her, don't respect her, and that she should file. She said she did, but I have yet to be served.
