It is actually true though that it isn't about OW. Something was wrong in the M - otherwise they wouldn't have wandered. They would have found another OW if they hadn't found that one.
Of course, that doesn't make OW's behaviour ok. Carrying on with a married man is just yucky and plain nasty and shows what they are really like. I hate the OW my H got involved with and even now, years after resolution, I hate her; I have just had to come to accept that. She is a woman of NO moral fibre. She even left her own H and small children to try and entice my H away - she was after his money and the prestige of his job. As soon as she saw it didn't work she went running back home squealing like a little pig - she'll do it again to some other guy....of that I am certain. If it's any consolation, they are probably being lied to by our H's as well whilst the A is going on. I think both the cheating partners are liars.
