I am/was married 11Y, 1 daughter 7 and close to finalizing divorce.
It's amazing the stories here since I have been lurking for months then actively posting and many are so similar it hurts whether M or F
I found the advice here great but I was too late and it seemed so counter intuitive. But your WAW already has her mind made up as she probably has been thinking about this for a while ..hate to say. By the time any relationship is at this point, the begging etc...makes it worse. I did the same, tried to force to therapy but she just wanted me gone.
Some of the board had pushed on the EA/PA which I could not fathom and while i snooped a bit could not find enough to firm it up. But I think many of these stories have some sort of "person" helping them get out the door quicker than they should or would without that interest. So I would not discount the "other interest' no matter how much they deny it..sorry to say. I found out now after 6-8 months that while she wasn't fully in a PA, there was enough with an EA to get her to gone.
It hurts and I am sure you know what you could have done differently but so could she. It is always a 2 way street so don't own 100% of the problem
Try to focus 200% on your kids and you. Some here have had success to turn things around with DB'ing. Hopefully it can reel things back in for you over time.
